I don't have any doubt that this was all just big pump and dump, but my theory is, even the BTC creators didn't realize that Bitcoin would go this far.
I agree to this. Basically no one can actually tell if Bitcoin will go up and down. But just like stock prices or even in forex. It is possible that the price will stay stable or even go up. Yes it may go down in some time but it will not drop price as be a dump.
Go down and dump are difference, a dump price on the market is a flash crash price of the asset you are trading. It happen very fast and 100%, it will recover after the dump be end (in a short time). But go down = bearish trend, it is mean this asset will drop down in a long time till the end of this trend, usually it is not end soon as the dump.
