Too Long; Didn't Read
Anyone who has bought cryptocurrencies recently has probably had to use an exchange, whether that was Coinbase, Binance, Kucoin, or one of the other many exchanges out there. It is likely that you had to use a combination of these exchanges — some for fiat pairs, some for the coins you want, and some for their trading platform. Throughout this process, you probably had to leave your coins on several centralized exchanges, in which they own your coins. This is clearly inefficient and potentially unsafe, and new platforms like <a href="https://coinve.st/" target="_blank">Coinvest</a> aim to bridge the gap between all of these separate services, creating one platform that can do it all.
