My suggestion is that you should invest in
1. Ethereum is currently the best altcoin after Bitcoin and Ethereum is also on the rise
2. XRP is also not a wrong choice because it is also being appreciated many times since it came out
3. Finally, Bitcoin is the most popular cryptocurrency today and after a bear market has dropped significantly and is showing signs of active recovery.
I see many people investing in XRP because of the achievements this project has made. But the fact that it makes you lose if you keep it from the beginning of the year until now, while BTC is more than 100% profitable, ETH is still profitable though less.
