This is a very good reason it is good to invest in good coins like just bitcoin, and also a very good reason to invest and not trade. Most people that lose in crypto are either altcoins investors and they did not sell their coins at the right time or they are traders which is very risky like how gambling is.
Either you invest in bitcoin or altcoin, you can lose, that’s why when investing or trading, you shouldn’t do that with all the money which you are having, we shouldn’t joke with our risk management when trading or investing in bitcoin.
Just because you are investing in bitcoin doesn’t mean it’s completely risk free, and we should invest blindly. If you are planning to hold bitcoin, don’t hold with everything which you are having, hold with any amount which you know if you lose, it’s not really going to affect you. Some people invest their life savings in bitcoin, some of them go ahead to take loan which they will find difficult to pay back if anything happens to the bitcoin, I don’t encourage things like this. Always invest with any amount which you can afford to lose.
