why people are worried about my investment more than me?

Why people are worried about my investment more than me, if someone know I buy crypto they will start tilling me to sell and start debating about it, I mean this is my hard earning money not your money in the end of the day my investments affect me only and the other issue is when they come to crypto community and start taking bad like reddit is full with forms if you don't like crypto then stop spamming it easily.
