What kind of stable market do you want? Cryptocurrency trading is very volatile it can never be stable unless trading is controlled by the authority to avoid market manipulation but since this market are free to control by anyone who has the power we will never be achieved its stability because right now it cant be controlled by any government organization.
I don't know, since Bitcoin first emerged, crypto prices have never been stable. in fact, even a very stable ETH is really unpredictable. well, but many people use this for their benefit. especially for traders.
