Choosing several types of investments is a good thing for those who make investments, of course it will be very profitable, if we only use all assets in one type of investment, this will be harmful to our assets, of course, this is not really what every investor wants. I think that in making an investment we need to leave our savings for unexpected needs, it is not good to invest all of our money so that we don't have money for unexpected needs.
In my opinion, treating Bitcoin to retirement savings is quite risky because the price of Bitcoin is volatile, and it is not uncommon for its value to fluctuate wildly over short periods. Additionally, because Bitcoin is relatively new and different from traditional investment, its long-term performance is still somewhat uncertain.
Instead, as a retirement investment, I consider investing in it long-term with continuous portfolio monitoring. We all know it can offer a hedge against inflation. Traditional currencies deflate value while bitcoin's value may increase over time, and also, it is a highly liquid investment. Unlike other retirement accounts that may require waiting until a certain age to access your funds, bitcoin can be bought and sold quickly and easily.
But still overall, bitcoin can be a viable retirement plan option for those willing to take on some risk.
