I would encourage friends to understand blockchain and encryption currency, but it is not a good investment opportunity, because the bear market has come, I would suggest they learn more knowledge, so when the bull market comes, everyone will make money.
Couldn't have said it better. However there will always be 2 kinds of people in the crypto world - people who utilize it for its actual functions such as anonymity, security ,and peer to peer transacting; and people who view crypto as a profit making scheme, which in any case would not be an ideal asset to hold onto due to its crazy volatility. Perhaps the reputation of Bitcoin being a "scam" came from those who consider Bitcoin for the latter.
