If you tell your friends and family about Bitcoin without giving them any sort of in-depth financial advice and they go ahead and invest, how do you deal with it when the market dips very low and they silently blame you for losing them money.
Every Bitcoin investor takes a high risk. Sometimes you can make a profit, but sometimes you lose money. All investors know it and are willing to accept it. For your friends and family, if they make a decision to sell Bitcoin, they may lose money. But before they go to Bitcoin, you tell them about the opportunity and ability of Bitcoin, they need to update the market, expert opinion from time to time ... you advise them not to rush to sell, wait a while they still make the final decision. I think you have done your best to protect their interests. You have no errors!
