In addition, all the risks that come from trying to persuade your friends and acquaintances to do something are simply too great to be worth the risk. In addition to volatility, everyone is susceptible to hacking of any kind or even physical attack - and if that happens to them, guess who will be the first to blame?
If I am a person who did attempts to persuade my family members, friends for introduction and invitation them joining Bitcoin market, I will feel happy if they succeed, but I will feel very bad if they got losses. They can have loss from tradings, using leverages, but I will not feel good if they had losses at all. So I will try to avoid doing such persuasive attempts.
In any market bull run, media is very noisy and these people will read many news about Bitcoin. They will decide to join or stay outside, it's their decisions, and if they need my help, they can ask, but I will not proactively reach out to them with my advice.
Bitcoin is truly something that has exceeded most people's expectations when it comes to price growth, and those who realized its potential in time certainly have far better financial stability today than others.
History of Bitcoin price makes many people over expect on its performance in a new market cycle. As new market participants, they lack of experience and it's hard to control your greediness and expectation in a bull run and no one can find a market cycle's ATH (All Time High) especially newbies.
By expecting too much, newbies will miss ATH, miss top price range, miss many opportunities to take profit during a bull market and they will stuck in a bear market with 2 or 3 years of so much price falls, FUD and pressure mentally. Many newbies will feel massively disappointed if they miss opportunities in bull market and stuck in a bear one.
