Yeah, but BTC is still risky in its own way, it can rise quickly, but it can also fall very fast, and there are so many investors who will panic whenever the price drops, because they cannot handle it.
BTC is surely a risky investment. BTC has high volatility, the price can change at any time. However, BTC is still a more secure than altcoins. BTC can survive well in crypto industry at least. Even if its has high volatility, its value always showed an improvement in every cycle (4 years-cycle). Everyone must know that every 4 years-cycle, BTC has a new ATH.
Those people who panic, they probably don't understand the cycle. If they know it well, they won't panic. Also, there are people who aren't ready with their mentality when they start BTC investment. So, besides having proper knowledge, BTC investors/holders must have mature mentality as well.
However, we can agree that some investors will prefer most of their money to be in something less volatile, like Gold for example, maybe because of their age or their desire for risk, even though they know the reward in BTC is greater in the long period.
Those people who prefer more stable assets, they probably don't know well BTC. If they know BTC offers more significant profits, they must try BTC investment. As far as I know, there are no other assets that offer huge potential profits as in BTC.
