Probably the guy who wants to buy huge amounts tries to prevent others from buying! What do you think?
I'm really not sure, it's strange behaviour.
I wonder if someone's doing this to prevent the price from rising too high too quickly and to try and keep the growth at a sustainable rate.
As a money-making strategy this makes very little sense, so I tend to agree it's someone trying desperately to cool down things. Whether to Bitcoin's benefit or detriment is unclear, though.
It also makes little sense to dump on a weekend or first thing on a Monday, yet that's also happened.
Oh well, someone loses BTC, someone else makes BTC... so the wheel spins round and round
Perhaps it's just an early adopter with more than 100k BTC at hand, there ought to be a couple of those guys around. Someone wants to buy a boat, I guess.
