Ripple is actually less volatile than most of other crypto (due to being so large in market cap size), so the argument of okan seems far from truth.
About the correlation of market cap size and the volatility, this is not entirely true.
Just think how the market cap is calculated... the total amount of coins issued is multiplied by the average of the last traded price among multiple exchanges.
In theory, XRP could have the same market cap with any shitcoin that issues a 13 billions of coins in the first block and then a single coin is bought by just 1 person for 1$. And there you have it, a 13 billion market cap coin is born with a volume of 1$.
I believe the main reasons XRP is usually less volatile is (A) because it's (arguably) more decentralised than many PoW coins that are mined from big farms in their early stages and (B) because a big amount of coins is held by a company that knows about finances.
XRP is a strange case of centralisation and decentralisation at the same time!
However it's not like XRP is not moving with the rest of the market when the market direction shifts, what I've noticed is that it's not affected greatly from daily spikes.
