Bitcoin is called a risky asset because of its volatile nature and that is why, one needs to invest with only the amount that he can afford to lose, so that if bitcoin price goes below his entry point, he can just ignore the price and keep on hodli. That is why it is advisable not to borrow money to invest in bitcoin so that you don't end up selling when it isn't your will, to avoid loss.
We saw Bitcoin price was stable at 30k USD few weeks back and then there is a dip triggered due to some news. Bitcoin in that DIP went down from 30k to 25k and that's the time where your nerves as a HODLER are tested. Its easy to say to HODL but not many can see there investment going down. That DIP is now over and Bitcoin price is moving up towards 30k again. If you have bought Bitcoin when it was down then surely you are getting some profit at the moment. Accumulating more when Bitcoin is down is more beneficial then when its up.
Exactly because when the bitcoin price is low, you have enough funds to invest with it and make a huge profit when the price rises, when the bitcoin price is low it is an opportunity for the investor to add money to their investment so that they will make a profit, Bitcoin is volatile and that makes it good to invest in my opinion, I can't call bitcoin a big risk because whenever I invest with it, even if the price goes down, I won't sell it because the price will rise again It is not like trading in which you will lose all of your funds if you lack knowledge about bitcoin trading.
