Coinbase is one of the largest Cryptocurrency exchanges in the world, with over 9 million customers.
-Brian Armstrong, co-founder and CEO of Coinbase
Coinbase is fully regulated and licensed in America. Founded in 2012, Coinbase stands as the oldest cryptocurrency exchange in the world.
Coinbase offers fair pricing and fees and includes debit, credit card and bank transfers.
My personal opinion is this, if you can, use Coinbase to buy Bitcoin, thier service is trustworthy. However, once you buy your coins get them the hell out of there and in to an interest account like BlockFi. That way you can earn 6% on your Crypto holdings.
