The movement of the coins does not mean that they are selling them or that it would have a impact on the price. I can move coins from one wallet to the next, without "selling" the coins. They could even move the coins through mixer services to confuse people.
Some of these coins might not even go through exchanges with the next excercise. A lot of people criticized them for doing that, so they might use another method that would not influence the price.
This is true,and I doubt that remain coins will be sold in the near future.For me,the reason is simple,price is too low and they will wait better price.Also I think I see some info that there will not be any selling of these coins in next 6 months,it is possible that this is not true.
Still I like this small project, we can follow all coins regardless if they are going to exchange or somewhere else.What I'm interested is something else,was it possible to track previously sold
BTC from MtGox or these addresses are available as a result of previous sales?
