If you think that's gambling is some kind of investment, you will always lose. Gambling is supposed to be fun and to be challenging. But it is not an investment. You should always think that you could lose a lot more than you will bet until one day you won something
That 10 bitcoins can be invested on more productive way but OP chooses gambling to multiply it and got failed but this story will make the others from doing it? Nop they will still do.
I heard that and that is a sorrow to see you loosing so much coins but I hope this year would have been good for you because if you still have some coins left, you would have made some money in the bullish trend and I hope the loss would be a bit compensated. Anyways, try to focus on the coins which are available in the market at low price like BNB and make some money.
