Even 1 Bitcoin is enough to change the life of somebody from a poorer country. It can be a large house in many countries.
I suppose while it is a giant prize, it is not going to be as attractive to so many players. I mean. A million sounds even better, but I would rather throw my money at a big win with better chances than basically play lottery.
As for me the prize of 1 BTC will always be attractive for a large part of the audience especially if such a prize can drop from the wheel on the Betfury site or any other gambling platform because after a few years the rate of 1 BTC can grow up to $250k and up to $500k and even up to $1 million. The only thing is that not every gambler will have the patience to hold BTC for so long, especially for those who got it easily.
This is somehow huge prize to be taken away if they get lucky and great achievement to get especially if they got this from those activities they actively participated like Free Fury Wheel if they got lucky to hit the jackpot.
Although not every gamblers really have a capabilities to hold long maybe due to their financial capabilities. But it would be good if they could able to hold at least half a bitcoin came from their winnings to hold so that they have some funds stake for future used especially that Bitcoin has lot of potential to grow on those figures mentioned.
Winning the 1 btc prize would be like winning a lottery. The winner should be wise to not spend all of that into just gambling again. Grabbing the 1 bitcoin secures your future already. It's already enough to you a good future if you manage to keep it for many years.
Not everyone is given the opportunity to have 1 bitcoin on their lifetime. With its price right now, having a whole piece of it would really be considered an achievement.
