I always share to my friends about crypto but i think when it comes to my personal earnings, it should always be in private. They may think that i'm boastful or arrogant the moment i share what i have been earning these past few years, so as much as possible i want to avoid it. Its better to stay being a low key person. And i don't want other people to judge me based on my earnings like i should live this way or not. As long as i keep my wealth to myself, i will always have the freedom to live the lifestyle i want.
It's true that they may think like that if you try to share your profits specially if it's quite high. You don't know what's on their mind whether they'll be happy for you or think negatively about you as there's this possibility that they may like to earn as much as you but you can't help them with that.
There are people in the circle of our friends that don't want anyone on their friends to go higher and above than them in terms of success and earnings and that's what I'm avoiding as well.
