Whatre the popular Altcoins crypto lovers are mostly using? Better if the coin has a low transaction fee too.
I think most traders now hold quite a lot of XRP. XRP really does not have too high volatility unless there are too bad news or the price of the BTC is manipulated.
For me, XRP is really a perfect altcoin. Transaction fees are extremely low and the processing speed of blocks is very fast. High liquidity and it is really good for traders.
