I think we'll be over $300 before Friday.
Anyone want to bet me 1 BTC?
I am in! I bet you 1BTC that the BTC price will be =< $299 by Friday 9th January 2015 12:00am West European time. We will take Coinmarketcap BTC Price as a reference.
Do we have a bet?
You owe me 1 BTC. When can I expect payment?
