Both cryptocurrency and real estate both are good both are important and one can not be neglected for other. Real estate is a physical asset while cryptocurrency is an online asset. You can be making money from real estate and be using it to invest in Bitcoin.
Investment opportunities are always renewable we can enter into Gold, real estate or BTC investments and of course it is not the last one for life if you feel late. I think the choice is in our hands and BTC as a hedge asset, if managed well, the results will be good.
Regarding future planning for boys and girls if I am given the convenience. I will open a BTC account for each of them from now on and when the time comes and they understand, I will hand over all assets to them so they can use them as best they can.
