Those who make terrible financial mistakes and put the blame on gambling or call it a scam process are likely to do thesame to other opportunities that seem like using money to get extra money eg cryptocurrency, trading currency pairs. Because you gambling without getting addicted is a function of discipline. It's a state of mind that you alone can build for self, so if you don't learn to control your emotions you end up messing other things up because of your mindset.
I agree with you; this set of people who always do this type of shifting blame and calling out a platform they fail to exploit are those who are too afraid to accept that they are responsible for their own actions; they always want to look for what to blame for the wrong decision that they have made in their life instead of accepting defeat and moving on.If they were able to win and be at an advantage, you wouldn’t see any thread like calling gambling a scam.
