Please can anyone explain to me the reason behind recent decline in bitcoin value and a sudden increase in altcoins to the turn that ethereum in particular move to the height of $325.16 of which it has never reach such a height in the last three weeks.
Your ideas are all welcome
My take on it is that the price of bitcoin crashed when the fork was canceled mostly due to FUD, at the same time bitcoin cash was pumped, part legitimately but mostly artificially, this only further fed in to the FUD around bitcoin. Altcoins especially ethereum saw a slight up turn because many people sold their bitcoin (obviously or price wouldn't crash) and then moved their money in to alt coins, ethereum is a natural choice being the second coin.
