Yeah, don't do this. You'd probably still make a profit overall, but only because the profit you make from bitcoin will outweight the massive losses you make on the other coins. You'd be much better just sticking to 100% BTC, or maybe a little bit of Ethereum as well. There is absolutely no point buying XRP, BCH, or BSV - they are all centralized scam coins, the first designed to make profit for the banks, and the latter two designed to make profits for their lying creators.
