everybody who sold at 11k will bang their heads on the table.
It makes at the moment no sense to sell.
And do not come with "sell high and buy low" where is high and where is low? Nobody knows. IF this would be that easy why we r not all be billionaires already?
They would surely bang their heads as of now for those people who did sell off on $11k price because price had risen and playing on 14k-16k ranges if we do try to look on chart. For now as of writing we are almost hitting 15k . ( 14,840) on preev.com. For those people who did able to buyback on those 12.8k usd price when bitcoins price tend to go down then lucky for them if they do make short trades since it would be an easy profit.
