It's becoming very obvious that somebody -- or more likely -- some government is trying their best to manipulate the price of bitcoin down. I would guess the most likely candidates are Russia, China, or .. the good ol' USA (perhaps a US - Israeli mutual effort). There aren't too many people out there who can afford to put up and replenish such ask walls, and who would want to manipulate the price down.
You seriously think a "government" is busy putting up walls of 500 bitcoins?
Not really, right?
Yes, I think it's very possible. I can assure you that there are many high level, closed door meetings occurring around the world about the rise of cryptocurrencies and the best strategies to subversively suppress growth. It is not in their interest to let this succeed.
And the best way to do this is by putting up 500 Bitcoin walls at 600.
This really sounds plausible to you? This is something a government would do to stop Bitcoin? You really, truly believe that.
Sorry for all the questions but i just can't believe you're not joking.
