What about you, do you think crypto scams in the country can be permanently eradicated?
No kind of scam in any country can be permanently eradicated, before asking such a question you can think about how would this be possible? Has any country gotten rid of scams entirely? I do not think there is even some example of that, usually even if some type of scam has gone away it is because it has involved into a new type of scam. The answer is definitely no.
P2P scams and ponzi schemes are very common in crypto and what are the ways we ought to be preventing them?
We entirely looking at P2P scams because it do happen daily and the vast numbers of traders and investors are crying out after been doped of their hard earn money. Loss is not good, absolutely what we all should preventing and doing everything possible not to fall into this dip mess. Falling victims of scams wouldn't make us any more happy because we're been scammed of our hard earn money, who will be happy that his or her money is been trickily taken from them? Absolutely nobody and I wouldn't even wish that for my enemies.
What do you mean with preventing the scams? Users or normal people should not be preventing any kind of scam, you should be avoiding them and minding your own business. You can't change the world, you probably can't even change your friends to make things even more difficult so what chance do you have of changing the world? From a personal point of view, avoiding P2P scams and ponzis is very easy. That is what you can do, actions that are limited to things that are completely in your control. I have never been scammed in P2P or ponzi, because with a few simple rules it is all avoided easily. Just do P2P with highly reputable accounts and you won't have an issue. For ponzis, anything that promises returns higher than 5% per year can be avoided. With those 2 simple rules, you will eliminate 99.9% of scam attempts on you.
