i'll accept your bet..... as long as the guide does not say "buy low, sell high and repeat"
He can't use that method because he cannot guarantee you would be able to sell or buy the Bitcoins.
What this bet is really about is the guarantee part of the deal not the doubling of Bitcoins.
Think about it, there are only a few ways to acquire coins:
1) Buy them. - Can't use that because there is no way of guaranteeing someone will sell them to you. That includes exchanges, because there is no guarantee they will be open.
2) Mine them solo or pooled. - Can't use that. Nothing in mining is guaranteed.
3) Steal them. - Can't use that. The exploit may be plugged. Not guaranteed.
4) Given them by someone else. - Can't use that. No guarantee that person will not change their mind.
5) Sell something in exhange. - Can't use that, no guarantee of a buyer.
