I agree with BCwinning with the point about bagholders.

Anyone with a noteworthy bag isnt leaving at a low, they wait for better opportunity. Someone who got their 50+ bitcoins when they were worth less than 10USD is not terribly concerned with dumping it (my situation, thus speaking from experience). They will wait because they didnt risk a huge investment in the beginning! It is more likely that the only bag holders dumping would be BTC miners, as they are more likely people who use it as supplemental income.
