This is so true and at the same time other people are complaining because they don't get paid their bounty. For what? For not being successful? It's ridiculous! Seriously.
They will be paid, but with a very long delay. Mavin could have set a bonus to bounty participants to reward their patience. The important thing now is to see whether the sheets are stored properly.
I agree with you, the data sheet should be kept safe to honour and reward every contributors and supporter of the project who has participated in the bounty to help market the project to global community. Every ico needs as many marketing distribution channels as possible.
