Do you tell your friends about your crypto earnings and trading strategy?
Of course yes, but it now depends on the kind of company that you keep and in doing so, you have to be careful not to relate your sensitive credentials to them and don't let them know all you've worth, i realize that most people tend to loose privacy into the hands of friends especially when under the influence of alcohol during hangout.
Sometimes it's hard to keep it to myself, but at the same time, I don't want to share my trading lifehacks.
Do you share with your friends?

Yes, i do share with my friends, especially on aspect i think will be of very important to them in cryptocurrency at large
