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
Just deposit in any exchange and do a trade. They will take just 2x0.01% fees and you will save your time to find another person plus escrow.
Or check whaleclub (https://whaleclub.co/)
whaleclub seems really pretty as site... it's a trusted site? There are just few stocks pairs with btc. Did you think they will add more soon?
Which type of documents they require for registration/Withdraw?
