Show up some technicals on this one rather than saying without having any basis.I read up above theres no significant support on 5k levels.
I'm already get used to when we do speak on bitcoins price.Im aint surprise that it can swing up 30-50% in a matter of a day or a two.
If it dips then you should accumulate and if it pumps then sell off for profits.Rinse and repeat then make some money.

He may refer to 50% fibonacci level which would be right about $5k which is correct in my opinion. 30% - 50% day up swing is not likely especially now in bear market. And about you "pump = sell" and "dump = buy" tactics - it is NOT that simple...
