Lots of big bear talkers here.
Who will take a $100 bet we do not see single digits by 2020.
Sounds like you haven't thought this through, OP.
Why would you, or anyone else, put $100 in escrow for five years, on the off-chance of winning $100? Sounds ridiculous.
@Blazr: make sure he escrows at least 10 BTC, because that's what you'll need to get $100 when BTC hits single digits.
