You mean Ethereum? Well, as I have read it had been esrablished for a long time so in terms of people's trust they already got it.  Stability? No. Why would you want that? I came here because I want to play with the price of crypto I see a lot of movent from it and that means money.
If you want stability. Buy a piggy bank then drop your excess money there everytime you have some. It will be stable. No price increase or decrease.
