Then Ill dump some coins and make it fall?
Hehe, I can see a film being made about this some day - the day people lost / made millions due to a 7btc bet

So really it's a case of who's wall is biggest? 7 vs 1?
TBH guys, this is a pretty silly bet to have when you don't know who the players are. Even sillier if you are the whale considering manipulating for this bet.
Its all for fun. I may donate my winnings to charity.
Or you could invest that 1 BTC in the most horrible altcoin you could find
