Hello, the best choice for exchanging cryptocurrency is an online cryptocurrency exchanger. But you need to understand that not all of them are equally profitable, honest and safe. You need to be responsible when choosing an online exchanger, because there is a chance of running into scammers with increased commissions or even a site that steals payment data. Therefore, security is the main factor for me when choosing a cryptocurrency exchange service. Recently I found a new crypto exchanger at Bitcoin & Cryptocurrency Exchange | Buy & Sell Bitcoin, Ether and more | Trustchange (https://www.trustchange.com/) , which has several licenses and is one of the safest on the cryptocurrency market.
