From what I can see these years, people tend to split in two major groups after being scammed. Some blame and say bad things also about Bitcoin, even though it is very different and has nothing to do with the projects that managed to scam them. Others turn into Bitcoin maximalists and they finally realize just how different Bitcoin is from altcoins and the scams that are made there.
Those people who take such incidents as a lesson and turn into bitcoin maximalists are the one who progress stronger over the years.
The ones who blame bitcoin and call it a scam are the ones who lose the opportunity of their life time.
We should be aware of what has happened, why has it happened and how to prevent it.
We should learn to accept our mistakes whatever the situation may be and try to improvise and only then we can grow stronger.
