I don't know why but I always get a feeling to gamble, after then losing my money, I quit for some time and then continue, but I know I will lose my btc

Why is it so addictive?
because you enjoying even if you lose, its a very kind of happiness
People enjoy the fact that they win after a red streak even if that amounts to a net loss but still its ok with the addicts since it fuels their addiction. There is no happiness in losing - everyone wants to win - the one who wants the biggest wins in gambling is the biggest loser. If you think you are going to be greedy and keep on playing then you are bound to lose.
