Only individuals with little or no knowledge of bitcoin are concerned about its volatility. Those who have been in the market for a long time do not panic when there is market volatility, but rather take advantage of it whenever there is an opportunity to buy more. Anyone claiming to know about bitcoin should not worry, but if they do, they may be considered beginners who are simply afraid of facing market reality after learning about it.
As an individual with a solid knowledge of bitcoin who's not concerned about its volatility - would you advise your friends & family to invest in Bitcoin more than they can afford to lose (or even go all in)? If not, why not? It's a sure thing, right?
