Only bitcoin could called stable coin because have good price every moment, with other coin like bch, doge, and bnb look do not stable price with lower. Bitcoin have potential become higher price and keep stable with moment where bitcoin become most profitable than other coin at the next time.
I take that you have no idea what a "stable coin" is. From the name itself, these coins are stable in value. The best example would be Tether. Bitcoin, on the other hand, is very far from being stable. Bitcoin is very volatile, which is the complete opposite of being stable. We've seen Bitcoin go up and down every single day. Your statement, though poses optimisms, is nonsense with respect to the topic at hand.
