Both coins that you mentioned are really great. But what I would suggest is start trading with a stable coin. This way you will get to know how this business works and when you understand the basics, then you can invest in any of these coins.
I am interested: how is it - to trade stable coins? They have almost the same price all the time, and very often, people simply invest in them to save their money from inflation. Bitcoin Cash and XRP - here I agree - are not the best variant, and as for me, Ripple is even the worst choice for now. Bitcoin and Ethereum are two reliable cryptocurrencies to trust and to deal with for years.
