Bilaji bold prediction that price will rise and put $1M
Assuming you own a considerable amount of BTC (say, 1000 BTC worth ~$25M), you make a daring forecast that the price will surge and wager $1M on it.
You realize it's unlikely to succeed, but you expect it to trigger a market rally. As a result, BTC climbs from $25k to $50k within three months. You lose the $1M bet, but your BTC holdings appreciate to $50M, netting you a $25M profit.
