Why not ,there alot of Bitcoin and others shitcoin casino run pretty steady so far now. But if you a gambler I suggest you to inform the admin to lock your account from gambling.
i think it can be risky specially if you are investing online, because there are so no guranty that the site can be really and will not be scam i think you first need to get some goo information about them and only then to invest.
It's all up to yourself, if you have some issues to trust someone online you can't make more Bitcoin. Bitcoin and online can't be separate. Unless you trader , selling and buying Bitcoin in cash term. Let me know if there any site that can be trusted. I have trust issues as well. 😀
