So, if you are one who skeptical about the genuineness of cryptocurrency trading websites, these numbers should impress you.

Verification is required; your mobile number and email would do that trick. Once verified, you can start making purchases, and you can use your credit card for that. The downside is that Coinbase is proud of its service quality and has high fees on its cryptocurrency exchange. Coinbase charges 1.49% from every buying and selling done. It could be more if credit cards are used for the purchase. It offers limited coins, including Bitcoin, Ethereum, Litecoin, ZRX, BAT, Bitcoin CAs, Ethereum Classic, Zcash, and so on. The interface is user-friendly, smooth to use. Your type of payment method may limit the amount of deposit you can make per week unless you do document verification on the platform. Verifying identity with documents raises the limit.
Binance
Binance is another cryptocurrency exchange platform that was created in China, and now serves most places in the EU. Getting started on Binance only calls for the “register” button, and you would type in your details, ready to start. Binance offers the largest amount of cryptocurrency pairs for trade and to buy. Because only crypto pairs are served on Binance, you will need to create a crypto wallet on their exchange to purchase and trade your crypto monies. Binance offers two trade options, which are the Basic and the Advanced trading options. If you are new to the game, then the Basic is the ideal one to go for, while you leave expert traders to rub their heads in the Advanced trading affairs. Trading commission costs about 0.1% on this platform, and it is even possible to get discounts. The only downside is that the verification can be slow. However, patience is a virtue when it comes to getting a trustworthy site to buy cryptocurrency online.
