I don't think so, there are more safe investments in crypto, trading as an example. This requires more time and learning, of course. But it's up to you to decide where to put your money.
Casinos work like this: while a lot of people are loosing, there are only a few winning big. Theae guys will never bankrupt the site, unless someone hacks it. Trading takes time and involves higher risks than investing in a casino.
I think its still the best to invest in trading even you are newbie better to study it and if you mistake this is one of the way to be success in the future.. no mistake no learning.. so if you just invest it in gambling and expect for earnings its risky because anytime gambling site can be gone hack or bankrupt..
