Coinbase is the best exchange.
Almost everyone said that changelly is a scam exchange.
Bittrex last year could not have a bitlicence in newyork.
Binance needs transparency , noone know where this exchange is realy based .
But Coinbase cannot be used by everyone in the crypto market. They only use it for Americans and some countries where Coinbase is based. In addition, if we are found to use fake IP, our account will be locked and our money will be lost forever. There will be no reports or any help from them! Therefore, from now on, non-US citizens should stay away from Coinbase. We have better exchanges, namely Binance, Huobi Global. They have huge reserve funds and transaction fees are quite cheap and we have many options when trading.
Coinbase wallet should only be used because this is a very secure wallet for investors and they will never lock accounts without specific reasons. I have been using Coinbase for over 4 years now and haven't had any major issues with me so you don't need to worry. Of course, famous exchanges like Binance or Okex are always welcomed by many investors and there are many ways for you to make money here.
