No matter how much you have saved in fiat bank, it will not make you rich unless you invest.
Saving your money is bitcoin is more profitable and valuable than keeping it in Fiats, but it doesn't mean that you can't become rich when you own more Fiats than bitcoin. The major reason why we are investing in bitcoin is to own an asset that has the potentiality of increasing our wealth in the future unlike Fiats that are relatively stable currencies that neither increase nor decrease but due to inflation, its values decrease as time goes on.
No investment is like Bitcoin investment. Both real estate, stocks, and gold cannot be compared to Bitcoin investment.
Bitcoin is a valuable investment that anyone will wish to venture into, but it does not mean that investing in some real-life assets is not good. Real estate is a lucrative business, and gold is also a good investment so while putting more of our wealth in bitcoins, we should not completely disregard other forms of investments. Besides, you can invest on real life assets and use the returns to invest in bitcoins.
You have practically said it all here, in as much as we love Bitcoin due to how trustworthy it has been in the past 15years we shouldn't disrespect or disregard other real life asset because I know of so many people out there that has nothing to do with Bitcoin, like they don't have a single fraction of Bitcoin but they are filthy rich due to the real life asset that they invested in, so on my own perspective I just see Bitcoin as one of those reliable investment out their that can make an investor rich if he can acquire a very huge stash of it and hold for a very long period of time.
Bitcoin is an opportunity that can be used to get rich if you invest heavily in it , not the only means to get rich.
Then as for the fiat, it's actually a terrible idea now to be holding money in it because inflation is his principal enemy that reduced it value overtime, so the best way to hold you money this days is to hold your money in anything that appreciate in value overtime, like Bitcoin, land, real estate, gold and diamond if it's possible to acquire it.
