bitcoin is the best money right now but what if after some time this will change? silver was once more popular than gold then lost its position. the british pound was once mightier than the US dollar but everything changes. of course bitcoin is still too young and has space to develop but in the crypto world everything can change so quickly that sometimes it's difficult to make long-term forecasts.
I don't base my life on just in case, you know? If you bet a lot of times on what is most likely to win in the long run you are going to get very, very rich. What is the most profitable asset that we know of today? Bitcoin (I leave out companies like MSTR here that can get an extra return on bitcoin in exchange for higher volatility). Good luck trying to guess an asset that will be good if bitcoin is dethroned.
To the extent that you are being genuine rather than just trolling, you come off as either distracted or maybe that you have no fucking clue what bitcoin is.
But, yeah, you are free to invest (or diversify) into inferior assets merely because you are having difficulties figuring out how bitcoin differentiates itself from them.
Wasn't it Warren Buffet who said that diversification for the sake of it likely demonstrates that the person has not done enough homework.
Good luck. You are likely going to need it.
Although we basically agree, I would like to point out that I do have assets that are not bitcoin. For example, I am not going to mortgage my RE to buy bitcoin, and things I had before investing in bitcoin, such as some gold, I do not sell them either. The new money I invest does, with the exception of my pension fund, which I don't have the option from Europe to buy bitcoin and put it in. So, I have a bit of a forced diversification, but the most important part is bitcoin.
