The bot may be partially responsible, but peoples greediness and unwillingness to part at 2x profit was the major reason for it actually going as high as it did.
Well let's be honest, if I wanted to make a 2x profit i'd go back to selling junk on ebay. I'm here for the 100x-200x potential profit in the long-run. People can call it greed, I just call it investing.
exactly 2x or even 10x is not going to drastically change my live.
100x might have a bit of an impact, but even than I'd probably hold most of it (at least what I don't need).
Bitcoin is likely to go up forever, because it's deflationary in nature. This is only going to get better with each halving.
