The only problem in online is cutting card you never know how deep your deck it....
You can never win over house in the long run in online casinos.
also you cant make steady profits from gambling ,its not a job ?
Yeah! Mostly, people thought that gambling brings continuous income or profit but actually now. Now every gamble wins their bets. So I believe that bitcoin is not a way to have a long term source of income. I suggest, when you win again, invest your profit to a more sure market like in bitcoins or turn that into a real business my friend.
Yes, if you are lucky enough to win in gambling, better cash it out and invest it to somewhere else or trade it. If you are not yet a trader, you can invest some of that earnings to learn how to properly trade with cryptocurrencies and start it from there.
