The future of the cryptocurrency business is as uncertain as ever. However, for the time being, it appears to be doing very well, and the presence of banks as well as millions of new traders and investors is undoubtedly a positive sign. The bull market's end could come at any moment, but most people assume it is still a long way off, and that now is the time to invest and take advantage of any chance.

When you purchase cryptocurrencies on a cryptocurrency exchange,, you're actually buying the coins. To open a spot, you'll need to open an exchange account, deposit the full value of the asset, and keep the cryptocurrency tokens in your own wallet until you're ready to sell.

Exchanges have their own steep learning curve because you'll need to get your head around the technology and figure out how to interpret the data. Many exchanges also have limitations on the amount of money you can deposit, and maintaining an account can be costly.

1. Dogecoin (DOGE)

Essentially, it was created to lighten up the crypto industry, which at the time was taking itself much too seriously. Not to mention the fact that it was mostly used by tech geeks and cyber criminals back then, putting it on a far darker road. DOGE was created as a joke to lighten the mood, and no one expected it to last longer than a few weeks or months, including its maker.

Musk has had his attention on the cryptocurrency market for a long time, however he has never publicly invested in it or endorsed it prior to 2021. He simply tweeted about it, using memes, jokes, and subtle references as usual. His voice, however, was heard far and wide as the world's most famous multi-billionaire. As a result, when Musk began publicly endorsing blockchain, he pledged his support for Bitcoin and Dogecoin. Tesla invested $1.5 billion in Bitcoin, while the price of DOGE soared due to Musk's frequent mentions of the coin on Twitter.

DOGE, on the other hand, lasted for years before exploding in 2021. Elon Musk, the CEO of Tesla (TSLA), SpaceX, and a host of other tech firms, who also briefly became the world's richest man this year, was one of the main reasons for this.

DOGE has also risen as a result of a Reddit-based group of investors standing up to institutional investors who were shorting a variety of firms, including GameStop (GME). Someone, who later turned out not to be a member of the group, tried to divert attention away from DOGE while the group was at its height of popularity.Its price soared to an all-time high of $0.085, setting a new record. For a time, this ten-year-old cryptocurrency was the industry's best-performing coin. All of this has shown that no coin can be written off ahead of its time, prompting us to add DOGE to our list of altcoins to keep an eye on this year.

2. Ethereum (ETH)

Everyone is familiar with ETH, which is almost as well-known as BTC in terms of its name. Its value has recently returned to $2,000, only to skyrocket even more. On April 13, the coin was trading at a new all-time high of $2,222 at the time of publication.

Although most people think of litecoin (LTC) when they say "silver to Bitcoin's gold," ether has been the crypto industry's second-largest cryptocurrency almost since its inception. As a result, it seems reasonable to begin compiling a list of altcoins to invest in with it.

This is Ethereum's biggest update yet, and it will fully overhaul the project, allowing it to switch from Proof-of-Work to Proof-of-Stake, introduce staking to users, and remove mining. Not to mention the numerous advantages to its network, such as increased speed and scalability.

3. Cardano (ADA)

This is the coin that has sat on the outskirts of the top ten list of largest cryptocurrencies by market capitalization for a long time. At least, that's how it would seem to a casual observer. Many that are acquainted with Cardano and its developers are aware that the project's team has been working hard on new changes that will revolutionize the project's blockchain and turn it into a technical masterpiece.

Cardano is known for taking it slowly and carefully, rather than releasing a half-finished product and then wasting years fixing the problems. It never succumbed to speculation or rushed to seize some flimsy opportunity only to lose everything in the process. Cardano kept its development process quiet for a long time and only recently began publishing updates that allowed its native coin, ADA, to grow in value.

4. Binance Coin (BNB)

In a nutshell, BNB is the Binance exchange's native cryptocurrency, and it serves as the fuel for the exchange's entire ecosystem, which includes subsidiary exchanges across the world, different channels such as Binance Launchpad, and more. The price of the coin has risen dramatically in the last year, from $30 to $550. It has increased by 42% in the last week alone.

Given that this is the year in which Binance Coin has climbed to become the third-largest crypto, outperforming Tether (USDT), Ripple's XRP, and ADA, it certainly deserves a spot "one of the top five altcoins to watch in 2021."
