well binance introduced using credit cards recently, coinbase does, and so does kraken. probably many others too. even with coinbase trying to eliminate themselves i still say its one of the better bets for that. kraken is nice and has plenty of coins, more so than coinbase. but kraken is a slow and clunky exchange. everything takes forever to do, and laggy. they upgraded the engine numerous times, but still just crappy overall.
