Bad experiences are not to be regretted, there have been many people here who had experienced negative or risk-like things, whatever you've been through... you're not alone in experiencing that, many people had made bad experiences with crypto... turn it into a better next step and more profitable. In crypto of course we can explore many things so that we can deal with them and also avoid some things that are detrimental. Crypto has many opportunities, even new people can get more than one chance to reap positive and profitable things.
If the OP will give up now, he may not see the true benefits of using crypto. He had bad experiences but it is his decision that made those bad experiences. If he will learn a thing or two from those experiences, he can use it to his advantage and get back those losses.
