Tell me, on which exchange do you buy cryptocurrency? For example, not so long ago I started making money with this and chose the exchange. As a result, I chose the KuCoin exchange, here is an overview of it https://tradersunion.com/brokers/crypto/view/kucoin/. I liked it because it is comfortable and has a lot of positive reviews. In addition, there is a minimum deposit of only $1. So I recommend that you buy and sell cryptocurrency through this exchange.
