Most likely indeed some of the thoughts in the future of ETH will be stable but not completely stable, yeah the more people know the crypto smaller the chance for profit but the rich are stronger so the stability I think will not be fully stable.
I think ethereum will never be a stable coin. or have a stable price. no one can control the price of ethereum. there are a number of stable crypto assets that may in the future be used as alternatives in virtual payments. but ethereum and etheruem markets will remain as they are now. keep moving and we always enjoy it.
Yes, ETH won't be any more stable coin in the market due to it's potential and the volume it is generating in the market. Very soon we are going to see some positive impacts in the market will surely help the ETH coin to increase the price of ETH coin surely.
Hopefully we will soon witness how efficient is this coin, and following with bitcoin's footsteps in generating more adoptions around the world. As people became more aware of this coin, the price became so valuable regardless on how each person used it with their personal use.
