When you tell people about BTC, you somehow carry a vague responsibility. If you feel that way, you must also tell them to sell to take a profit when the bull market is almost over. The blame will be worse when the person you convinced to invest in BTC is your close friend. You don't wanna lose that trust and friendship.

I feel ashamed of one of my colleagues when I told him to buy XRP back in 2016 and not send a notice to sell when the bear market started in 2018.
I took the responsibility too. I always remind my sister to sell the coins that I sold to her because I don't want her to suffer the same fate that I did in 2017.
