from what i was reading, if someone puts huge numbers of bitcoin out there, it would crash the market. people will start selling it too in fear of what can happen and bam, bitcoin is spinning down fast
Maybe if Satoshi himself would put his 1 milion btc on the market that would happen. But remember when people are selling there is someone who is buyng..so bitcoin will switch from weak hands to stronger hands.
Anyway i dont think this is a real issue...
