Doubling my $40 in four days will definitely make the risk worth. I have my car insurance due in January so I'd might pay it with XRP bull :)) If not, I'll simply let the bet age and the next year it will for sure become a winning one.
A good idea, I hope you can do it because having this mentality is risky but I consider that in life there are times when we must take risks and that is what makes us winners.
I wish you success in your bet!
