Bitcoin has proven to be the best investment over the years, and nobody with a good knowledge of Bitcoin and cryptocurrency in general can deny the fact that Bitcoin is not the best investment. Considering what early investors have made from Bitcoin since its exitance, I don't think it can be compared to any other investments, such as real estate, gold and others like that.
I think the best investment will depend on each person's needs. If you are looking for high returns and are willing to take risks then bitcoin is clearly the best investment. But for investors who have billions of dollars in hand and what they need is a safe asset, it is clear that bitcoin is not suitable for them, gold or real estate will be more suitable and they will be the best investment for them.
Just because you invest in bitcoin and it's best for you doesn't mean you can impose your thoughts on others. Each person's needs and thoughts are different.
This is the right balance people have trouble with. Some people think it's like gambling and they are fine with it, so they get in, and see bitcoin isn't gambling, so they do either x100 leverage trades or they do memecoins and what not. Some get in and think it's like gambling and they think it's too risky and get out and not really invest anything into bitcoin.
It has nothing to do with gambling ,there isn't a "risk" in gambling, there is a mathematical guarantee that you will lose your money at gambling. In bitcoin however, you have a risk, sure you could lose if you invest at a bad price and it goes down and you sell at a loss, this happens and it's understandable and we could se this happen again, but it's a risk, not a guarantee for you to lose. If you can be careful and invest carefully then you can win. At gambling, even if you win a few times, the longer you play, the higher chance you are going to lose it all, mathematically there is no outcome other than you losing if you keep gambling.
