Hello everyone,
Would anyone like to make a bet, without any escrow or anything, on the direction of the bitcoin price over the next 24 hours?
Anyone who wins against me can give me an address. And I'll TOTALLY send you BTC, and not just abandon this account and laugh at the fact that you made a nonbinding bet and expected me to pay!
Meh, I have a better bet and I really WILL pay, no trolling, no jokes:
If in 2020 bitcoin goes to less than $0.01 per, I'll send you 100 bitcoins.
If in 2020 bitcoin goes to more than $1000, you pay me 100 bitcoins.
