Coinbase is a centralized exchange that is very popular and used by crypto traders most especially those in United State. Coinbase was founded in 2012, 3years after the release of Bitcoin's code in 2009. Coinbase fully regulated and licensed cryptocurrency exchange that operate in over 40 U.S. state and territories. Coinbase offers insured custodial wallet for traders and investors to store their Investments. The Coinbase custodial are very expedient for newer users who are getting into the crypto space, although the private keys to the coins within them are controlled by Coinbase, and not the trader. The reason why I choose Coinbase as my second best centralized exchange is that Coinbase has a high liquidity, very simple user interface and variety of altcoins for one to invest in.
