Perhaps Bob is double bluffing and he is pushing too, but this is most unlikely.
Lin and Bob would have the most to gain with this. Lin owns the most Bay and Bob apparently has a large group of very unhappy schemes on his tail. Those that would want to continue Bitbay in whichever form they think has a chance would be served with a modest buy-wall. This is not a buy wall however, this is a very tiny trading volume pushing the price hoping to bait any unaware trader into buying.
You can break it immediately by setting a buy wall underneath them of course, but then again they have enough capital to eat it and continue the game again.
You could be right. Regardles who is creating the fake volume again, it's is quite pointless to discuss whether the scammer Bob pushing the price up or the scammer Zimbeck or the scammer Steven Dai. It's like when one part of the community is arguing that the scammer Zimbeck is a more trustworthy individual than the scammer Bob.
