I want to make a bet that ETH price will rise more (or lose less) value than BTC over the course of 3 weeks/ I'll give you 2.2 value on Bitcoin. We will either use a smart contract or escrow for this bet. I am willing to bet upto $300
What's with this idea of your bet anyway? I don't even understand how did you decide to come up with this kind of idea? I feel it's absolutely stupid for someone to accept this kind of bet. Where one looses, however if you make a better call and invest 300$ in Bitcoins or ether you'll stand to gain, I don't like alts but only since you're keen. Otherwise I would tell you to drop this ridiculous idea, only a fool would enter this kind of bet, and I don't think anyone here will.
is he pertaining on the %gain/loss of the two currency? the bet is quite high. somehow hard to predict.
