Bitcoin is only risky when you have in mind just to invest to make quick profit, so far as you have the understanding that Bitcoin investment is a long-term investment you will definitely get profit in hodling.
This is the mistake newbies make with bitcoin. They've refused to have an understanding of bitcoin. They see bitcoin like every other altcoins or memecoins which are mostly not good as advertised.
With bitcoin, you have to be patient. You have to play the long game. It's a way to have a long time asset or investment.
In a short period, bitcoin might increase by just 2-10% and except you bought a huge amount of bitcoin, that's not a lot, but if you're patient enough for at least a circle,you might get exponential profit. With this you can easily take out your profit and leave the actual money you invested initially.
DCA is the best way for people who aren't that rich but a lot of people still don't rate it, they want quick profit.
