Of course, this is a ripple from the whole list, both in its technology and price it stands out among the rest. But there are other coins like lisk or stellar. Some prefer the non-top-end graft.
I feel that bitcoin, ETH, and XRP are the coins that have the best stability. although indeed the price sometimes rises very high, and decreases quite severely. however, among all the coins, I feel that the 3 coins are the most stable coins.
