5 Cryptocurrencies You Should Consider

Do you want to skip the read and get right to our top picks? The best cryptocurrency to invest during 2021 is Bitcoin or Ethereum

While Bitcoin is the leader, both by market capitalization and daily volume, it is not the final word on cryptocurrency. With the success of Bitcoin, a plethora of altcoins sprang up, making it difficult for investors to choose the best one. In fact, the cryptocurrency market is currently flooded with more than 7000 coins.

If you don't know which coin is the best for your investment portfolio, we are going to show you the top cryptocurrencies in 2021. Here are just a few to consider:

  • Bitcoin (BTC)
  • Ethereum (ETH)
  • Cardano (ADA)
  • Ripple (XRP)
  • Dogecoin (DOGE)


If you are looking to expand your investment portfolio with a piece of the crypto cake, we believe the following options will be the best fit.

Top cryptocurrency for 2021: Bitcoin (BTC)

Bitcoin is arguably the standard in the crypto market right now. There is a good reason for that. With an all-time high price of $68,789 and a market cap of more than $922 billion, Bitcoin is making it impossible for other cryptocurrencies to keep up. The blockchain leader has dominated the market since its inception in 2009.

While Bitcoin has had few bumpy rides along the way, its price continues to surge, making it an even more alluring option for new investors. 2021 was a great year for Bitcoin.

In April 2021, Bitcoin was trading at an all-time high price of $63k. Six months later, that price surpassed the $68,000 mark. It is clear that the other cryptocurrencies have a long way to go before they can achieve the milestones that Bitcoin has achieved.

With such an outlandish market cap and a daily volume of roughly $30B, many crypto pundits will no doubt be pouring their money into Bitcoin. Already, well-known public figures in the business world, companies, and institutions are warming up to Bitcoin with billions of dollars in investment.

So, if you are looking for a cryptocurrency to invest in that millions of people trust, you wouldn’t want to look beyond Bitcoin. However, with the now high price and overcrowding, it might take a long time before you can start thriving. So, if you are not in this for the long term, consider our other options.

Ethereum (ETH)

While Ethereum boasts of a market cap that is 2 times smaller than that of Bitcoin, it has been invariably lauded as the most promising cryptocurrency this year. This is the second biggest cryptocurrency worldwide, both by market cap and daily volume. Ethereum’s advantage lies in its focus on superior technology as opposed to just being a digital asset.

Unlike Bitcoin, Ethereum is so much more than just a cryptocurrency. It is a platform where other developers can create their own digital assets using Ethereum’s tech, such as smart contracts. This adoption of other Decentralized Finance (DeFi) has made Ethereum a hot cake in the crypto market.

Although Ethereum’s current price is significantly lower compared to that of Bitcoin, it is quickly rising and getting the attention of more investors. Ethereum hit an all-time high price of $4,891 in 2021. This is a significant surge considering that it was only slightly above the $730 mark in the beginning of 2021. 

So, while Ethereum is significantly junior to Bitcoin, there are a few things that make it a better cryptocurrency. For starters, it is blazingly fast. A transaction that might take 15 minutes with Bitcoin will only take 15 seconds with Ethereum. This makes it an ideal option for real-time use instead of merely being a store of value.

According to Crypto experts, Ethereuim is worth buying in 2022. The digital asset is expected to grow even more this year. This means it will be getting the attention of more mainstream investors, and soon the Ethereum bandwagon will be bustling with successful investors.

Cardano (ADA)

Established barely three years ago, Cardano has risen to become the world’s largest third-generation cryptocurrency. This is the best option for investors who are looking for young crypto with plenty of potential for growth in 2021.

According to data from CoinDesk, Cardano enjoys a market cap of $29.21B with an all-time high price of $1.20. This is significantly lower compared to our two options. In fact, it is so small that very few people already know about it. And as much as this may come off as a red flag, it is actually a sign of great potential.

ADA prides itself on some of the most exciting technological advancements in the blockchain industry. First of all, it runs on a proof-of-stake system which means that it is more efficient than the proof-of-work alternatives. Proof-of-stake basically means that the more ADA you have, the more mining power you have.

Just like Ethereum, ADA also heavily relies on smart contracts to easily handle payments and keep track of transactions. This makes an ingenious combination of both Bitcoin and Ethereum. So, although ADA has a lot of work ahead before it can reach the league of Bitcoin and Ethereum, it makes for a great investment for early adopters.

It only took Cardano three years to hit a market capitalization of $10 billion. This was much sooner than it took Bitcoin to achieve the same. This means that Cardano is quickly picking up momentum, and soon investors will start to pile in.

4. Ripple (XRP-USD)

Established in 2012, Ripple’s XRP makes for an easy bet for investors looking to start buying in 2021. According to the experts, the coin has the potential to double its value 10 times this year. XRP has already hit the $3 mark, which most of the other cryptocurrencies are struggling to achieve.

With a market cap of about $24 billion, XRP subscribes to a slightly different form of operation. Instead of being community-managed like Bitcoin, XRP is centralized and is only mined, controlled, and administered by its creator, Ripple Labs.

This gives the creators control over policies and the ability to execute trades quickly and negotiate with mainstream banks. However, this approach has been met with a lot of criticism as it seems to deviate from the very essence of a cryptocurrency; decentralization.

Despite this, XRP has shown a lot of potential and promises to be a good investment in 2021. It is now being used by some financial institutions in place of the SWIFT network giving it real-world application and widespread adoption.

The coin picked momentum in 2017 when it grew 36,000%. That is, raising its price from nothing at the beginning of 2017 to $2.4 in December that year. 

5. Dogecoin (DOGE-USD)

Dogecoin started as a joke. That is about what anyone who has been in the crypto market long enough will tell you. However, the joke can only go so far. Dogecoin is actually a pretty serious investment for traders who are just getting their feet wet.

Turns out, the initial virality of the Doge meme paved way for Dogecoin in a market where giants like Bitcoin were already towering. Now, with a market cap of about $7B and an all-time high price of $0.087, the DOGE is set for slow yet steady growth. Apart from its meme popularity, the main attraction of Dogecoin stems from the fact that its price is continually increasing.

So, if you invest now, you are exposed to higher profit opportunities than other coins. In fact, like many of the other cryptocurrencies, Dogecoin is already starting 2021 on a profitable note. Endorsements by business gurus like Tesla’s Elon Musk have skyrocketed Dogecoin’s value making it one of the fastest-growing cryptocurrencies.

The newfound popularity seems to have worked well for DOGE as more investors pile in. However, being a relatively young cryptocurrency, Dogecoin is still highly volatile. So we advise that you only invest in it for a short time and take your profits as soon as they come.

The coin will probably keep rising in 2021 and might soon hit the $1 mark by the end of the year. This is as long as it keeps growing its user base, maintains internet popularity, and sees more worldwide adoption.

Factors to Consider When Choosing a Cryptocurrency to Buy in 2021

Like with any investment sector, the cryptocurrency market is highly dynamic. However, despite the constant price change, market cap, and adoption, there are a few factors that, when you observe, could be the difference between profitability and loss.

Let’s quickly look at some of these factors.

Market Capitalization

The size of the market a cryptocurrency controls can hint at its liquidity. The higher the market cap, the safer it is to invest. A higher market cap usually means a higher adoption rate and that more people are investing in that particular cryptocurrency.

So, if market cap matters in your investment portfolio, we recommend investing in Bitcoin and Ethereum.

Adoption Rate

If a cryptocurrency is widely being used in real-world transactions, it means that it is trusted and has more profit opportunities. So, if you care about mainstream adoption, you might want to focus on cryptocurrencies such as Bitcoin that are now widely used in businesses, insurance, and investment.

However, being speculative investments, it is possible to find more plausible breakthroughs with newer coins such as Dogecoin and Cardano.


Some cryptocurrencies might have higher mainstream adoption with enviable market caps but do not have the right technology for your unique investment needs. That is why it is important that before choosing a coin to invest in, ensure that it has the features you are looking for.

For instance, Ethereum and Ripple grew quickly by focusing on new technologies that other cryptocurrencies were not exploring. So, you might find that these are more suitable than Bitcoin because they have the technologies that will help nourish your investments.


The main attraction of blockchain technology is the anonymity it offers its users. This means that you transact anonymously and enjoy the freedom of decentralized finance. Other security features, such as the smart contracts offered by Ethereum, ensure that transactions are more secure and fraud-free.

Being a highly risky investment, it is only logical that you consider cryptocurrencies with better security features.
