the price of etherium is not yet stable, there is still too much down and there is also info that the platform of etherium will change.
Well this is true that price is not stable now a day but I am sure very soon it will be good. We are the in 2018 and soon it will be 2019 so have patience and wait until the market covers for ETH. To be honest I am just aware of price fall but not about the platform change... so about price I think this is golden time To buy and store.
