I would like to find out because I would be really interested to know when they will be selling in the future and how much. If you have any ideas or info how to go about that, let me know!
People who are new to bitcoin don't care cause they "only invested $1000" but then they realize they are paying with their Mycelium wallet since 2 years and their transaction history always involves one address and they moved a fortune worth of coins due to price increase

I think he was that was just an attempt to plug his wallet software (it's in his sig). That made no sense in context.
