That's true there is no safe way in gambling, you can reduce the risk but still it will not guarantee you to reduce the losing chance.
Trading is much more safe rather than gambling.
it right, safe gambling does not mean you can not lose. safe gambling is the least you can always make a profit and right, you more winning than losing. despite the advantages of victory was not great, but at least you can win in a productive.
You are wrong imo, there is no way to always make a profit on gambling. Safe gambling should not be considered like that, because that does not make any senses/impossible. The most possible thing is that you can minimize losing instead of always make profit.
