When we are not being greedy, I believe we can stay safer without getting scammed.
Only due to greedy, people are looking for high yielding investment opportunities and finally getting scammed.
Yes, people who are greedy are getting scammed very quickly compared to rest of people. When we are rushing for making money in quick time, we are all getting scammed so quickly. We must control our emotions by remember the fact of easy money is always work as a bait for a big trouble. For investments, we never try to find options so quickly. We need to study them very carefully before making any decisions.
Instead of taking risk with some unknown entities, why not we just trust only bitcoin kind of decentralized opportunities. Because, we can do nothing about the investment opportunities which are derailing in middle. Like you said, studying them carefully about their past performances will not help you to guess what is waiting for you in future. Being simply bitcoin holder is much better option rather thane being a struggling bitcoin investors.
i understand your point mate, but for me its still better to try some risk if you wanted to explore with crypto investment having some knowledge and learn from some review will help us to benefits in return, but always stay with simple principle invest what you can afford to lose.
