Yeah you are right investing in altcoin and doing trade with bitcoin is more better than investing in gambling as in gambling we face a high risk and mostly peple lose their money because of scam or something else, while in trade we are oir boss with having control on our money.
Tell me one gambling site that took investment and run? When you trade on exchange you not have control over your crypto, but your exchange has. And i seen a few exchanges go bust.
EveryDice is one. There was another dice site I can't recall the name of, it was run by a Russian guy. Dicebitco.in maybe? If that's not it, it was something close to that. Truth is, there have been a great many investment dice sites that have run with money. I know there are more than these two, I just can't recall the names of them all because they all blend together.
I know Dice Ninja was a big one
