Not in general but in any opinion gambling should never be considered as an investment because the ones who gamble often get so involved in it that they forget about the risk of losses. Many gamblers lose thousands of dollars per day while investors can't risk to lose that much.

An investor should always have an active approach towards investing because even in case of minor losses the investment becomes a failure. I think it's way better to directly invest in an asset like Bitcoin rather than investing in gambling at all. However, if someone invests to make a casino then that's another thing.

In gambling such investment will always turn out as a failure and someone should most probably avoid it. Gambling should be done just for sake of some entertainment and gambling responsibility should be incorporated each time when someone gambles.
