It's the fact that gambling made easier nowadays. But it's not only limited to Bitcoin.
I think that most gamblers that are losing their control will fall for their own trap. No other than set it up for them but it's them. Because it's not always the choice that we do.
But the actions that we do, so whether you gamble with Bitcoin and you see it as an opportunity to add more of it once you win. However, we don't have control of the results and that's why we still lose both of it, so we still fall for own traps that we make.
What a one way street that posses indeed as a two way, to the system, multiple daily transactions from gamblers helps the Blockchain technology grow. So, on a general ground it's helping the system, but on an individual status, gambling is detrimental to personal portfolios and most players I've read that gambled with Bitcoin regrets it, because it's an appreciating money. Except that, players who gamble with fiat also feel the effect of losing money. Hence, gambling is a trap, not just for the Bitcoin players alone, the mental approach to it is what determines what it's like for any gambler.
