It is very funny to me that anyone says it's more risky for bitcoin, it's interesting how they can say it. Such large institutional investors would not invest in bitcoin if he thought it was too risky. Just looking at the 10-year chart is enough, the real risk is the meme tokens and similar ones on the market right now. The choice of Bitcoin is always profitable no matter where you buy it in the long run, this is not open to discussion for me.
Of course what you are saying is something that must be understood and used as a foothold for those who want to start in crypto. that bitcoin will not experience the risk of loss if you want to be a long-term investment, because it is certain that every 4 years there will be an increase in bitcoin. So if you want a long-term investment, it is very good, but the problem is of course the funds that must be deposited are quite large.I also have almost the same meaning as what you say because if Bitcoin can be a risk, then others can be a disaster and a nightmare, so this is what some people need to understand and especially those who say Bitcoin is risky. 
actually everything in crypto is very risky and it is a natural thing to be careful about. but the risk just depends on the coin and the treatment we will do. if we invest bitcoin the long term, at least once every 4 years. it is certain that it will not experience any risk because it will definitely increase in price, but if it is another coin, of course there will be a risk.but if you want to do bitcoin for short-term trading or daily trading, it is clear that you will experience a very large risk, if do not analyze it properly. because the movement of bitcoin is very fast up and down, so the risk of the impact can be large if the analysis is wrong.
