There are more than 1000 altcoins in the market. What do you think for the most stable altcoins?
Actually for me, there is no altcoin that considered as stable but there is one coin that nearly as stable as it seem and that is ethereum because even though the market is down it has still a good potential.
I am sure that Ethereum will be more stable in future as some other top cryptocurrencies. But in my mind the time when it will happen is hardly can be predicted. Market is in the mist really. That's too difficult.
