I'll give you a very open and libertarian bet: If IOTA hasn't achieved 'success' by within the next 2 months I am willing to pay you 100 BTC, if you're willing to pay me 100 BTC if indeed IOTA is a success by then. It's a very simple issue, if you honestly don't trust my vision and skills. Your move.
I haven't trusted your business skills for a lot longer than two months... this bet can't be retroactive can it?
Take the bet, lower the amount if you like, but for a guy who talks a lot, you need to back it up with some conviction for once. If you don't like gambling agree with iotatoken to donate the 'prize' to a charity of your choice
Honestly, I don't think David has 100 BTC of his personal money to "gamble" like this. Investor money maybe, but not his own. Normally, I'm morally opposed to "gambling", but I'm having a personal crisis right now determining if this would really be considered "gambling".
