Thank you for replying! To be clear, I mean to sell LTC (€51) for XRP (€0,21). Both of them are going to grow in a bull market, I hope, but which of the two has the better cards for this grow?
During the 2017 bull run and beginning of january 2018, XRP went from 0.20 to $3.40, that's a tremendous growth. In that year, LTC all-time high was $360 according to Coingecko
[1], that would be a 500% increase from the current price ($60). Pick your poison. But i would listen to the other users and keep an eye on Ethereum, just saying...
Remember, don't go all-in on a single crypto, diversify your portfolio.
