It is normal to fear investing if you're not yet knowledgeable about it. It's better to take it slowly and learn as much as you can before putting any money even in bitcoin.
That's right, I can't even imagine the feelings of people who bought bitcoin at its peak price and see its price now. Although, most likely, these people knew all the risks when they bought it.
Speaking of that situation, I've seen people that did the same thing and it was not just during 2021 bull run but also on 2017. It's truly a matter of patience when you invest aside from having the knowledge of what you're buying.
So, if you ever decide to buy, you have to make it sure that you're firm with that decision of yours and you're going to hold as much as you can until you profit.
Yes, this niche obviously requires a lot of endurance. I've heard stories from friends when people made a good profit on their investments and went to trade futures, after which they just couldn't stop and lost everything they had earned, and sometimes everything they had.
