Because it's the #1 reason we still get "Why am I not getting my tokens?!" emails
Are you re-investing those crowdsale BTCs ( or at least a part of them) into wallet/project development?
Your website said the project is valued at around 60k BTCs including the 5k from crowdsale, wouldn't you get more profit to develop and get that value higher than to take the crowdsale BTCs for you acting like if it was profit you took from selling 5% of your stock value?
Why do you think this worths 60k BTCs? (sources)
Is there any other source of profit for this company besides ads that could be put in the wallet?
