All I can say is if you look at the charts
Probably you are right, but stable? It is not stable, the price made more than x8 since August, maybe more than x15 since the beggining of this year, but that is exactly the opposite of Stable.. It is very volatile, i think that you mean that.
Monero is the most stably increasing coin.
That is what i mean, if i am not wrong, it was less than 15 bucks on January, it is incredible.. And in the last few weeks it went from $150 to $240.
(look at the graph from the start of the coin.)
But Zcash is the most anonymous coin that you can use, and it is cheap
