Exactly we don't need to get regretted on those things which have related to the cryptocurrency. Instead of that, we have to learn from those mistakes and never have to repeat the same mistake.
I think regret is that the most important human nature is always learning things that happen, including if you get a loss and make the loss a valuable lesson
This will apply to people who have experience in the crypto world differently from people who are just learning how to invest and this will make a big downturn for them later.
Guys, be practical on some point of your life....
You don't need to encounter mistake first before you learn about specific things or situation. You can learn from the mistake or experience of others, because most mistake on this crypto currency is for being idiot and lack of knowledge on this kind of league.
One good example is : If you are a doctor, you don't need to feel the pain or the to be ill if you want to know the cure. The cure is already on the books who published by other doctor etc. All you need to do is to teach your self and be careful to understand every detail of it.
Hope this is a little help on you guys. God bless
