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.
True, Mr. Satoshi Nakamoto the creator of bitcoin, the reason why we are here now didn't realize that bitcoin will go this far. In my assessment the only reason why bitcoin value reached what it is now, it is all because of the whale investors, or big organization that has a capacity to Pump and Dump the price of bitcoin. Or other big exchange sites who bought a huge volume of bitcoin.
