Still can't understand people. Bruh why choose one if you can have them both at the same time? You can split your money, 50% cash and 50% in btc or depends on how you split your money. With that, you won't regret any of those two for your childrens future because you chose both.
I don't know if it is safe to call if one would do that, splitting his money between bitcoin and cash, but for me it is. Both investments possess risk and I know that bitcoin is more riskier but can be more profitable. I think many people have done it already but since bitcoin is still on dump, they can't say that they have already earned a profit. When it comes to saving, there are many methods but investments are much preferable because of the profit gained over a long time.
As of now, we have investments by cash/real estates and bitcoin to choose from but if you have the money then investments through cash and bitcoin can be done so you can gain both the benefits and advantage that both methods can give.
