I think the bet amount is not the most important thing he want to share, but he want to say that winning streak on 2x payout is possible.
Bet amount is the important thing in gambling. There was a guy who won 100 btc just in a bet, do you think it's not important compared this "14 winnings streak"? Or do you prefer win 14 in a row with small amount than win 100 btc in a bet?
Imagine if he bet 1btc but he got losing streaks? LOL
He will lose 14 btc. Why?
