Yes both of them are risky, but Altcoins have more risk than Bitcoin
Bitcoin is not risky.
If you are losing, do not sell but buy more bitcoin instead. If you continuing buying it like DCA, you will later finally conclude that our mind is only deceiving us, and accept that bitcoin is not risky.
Also you will conclude that fiat that looks stable is what that is risky.
You’re absolutely right, bitcoin isn’t risky when you do the right thing when investing in bitcoin, if you’re buying bitcoin on a regular basis and buying through the DCA techniques and holding for a very longest time, the fact that bitcoin is volatile in nature means there is a bit of risk involved but you can manage the risk involved.
But there are people who follows the wrong way by investing in a short term, and likely trading bitcoin that is when investing in bitcoin is more risky, I can’t take away bitcoin as not risky, but we can be able to manage the risk involved while investing in bitcoin.
There are individuals who doesn’t understand what bitcoin is all about, which is why they make the wrong choices when investing in bitcoin.
