i also have learned that giving out unsolicited advice will just bring you more harm than benefit many people do not appreciate being 'lectured' and they will take offense if you tell them what you should do
on another hand if someone does try your advice and it doesn't go well, they might blame you and even ask you for compensation you would be surprised just how entitled people can get so it is best to remain silent and mind your own business
Actually what I think about advising others, no one can assure or guarantee that he or she can bring you 100% trading skill and by doing that you can earn a lot.
I would say no one can teach anyone anything unless that person is willing to learn. I would say the same thing about trading and all things that if I give someone advice I can show them the way how to learn something and where you can improve. But to be successful, he must give a lot of time and of course he can't give it time and leaves the market after failing.
You have spoken really well, only those who open their heart and mind to learn, and actually go home to put that which they have been taught into practice, are the ones who usually learn and become good at that which they there taught.
It's like helping someone, you can really help a person who have not agreed and given him or herself up to be helped, you forcing your help on them is equal to you wasting your time.
So, when it comes to cryptocurrency investing and trading, definitely only those who dedicate their time to learning, disciplined themselves enough to stick and never give up, this ones are the ones who definitely will make headways on the future.
