I think that was some of the best thing to do with the winnings.because if we kept it for the another gambling time.there will be a possibility that it will be lost.so by then we cant call it a winning.
But if we buy the important things . We can call it a winning already.
That id you win a big amount however to win a big amount, you will need to wager alot as well. High risk is equal to high return however if you wager 1 mbtc and hope to win 1 btc then you wont win anythng at all because most likely you are going to lose everything because you keep on wagering
