Because we are all not sure if this predictions will come true in year 2025 or in the future there are two results that may happen to all hodlers of bitcoin who put their money 100% in it, either they will become a millionaire or become a homeless soon lol but I hope OP is correct.
that is the risk when you invest, you dont know what will happen to your investment especially it will run for a couple of years it is good if you will became a millionaire by that year but also you should look the in the moment when you will have nothing to earn from your investment, 5000$ is a huge amount so people must think of it before putting in an investment that there are no assurance of having a positive profit.
