No we are in a fiat bubble that is about to burst. Just search purchasing power of dollar and supply over the years and see what that means.
The smart ones will invest in land and other solid assets such at bitcoin to hedge against what is happening now. However they will make you believe to keep saving and investing in fiat based assets until the rug pull.
You know, at some point I start thinking you are trolling, but, just in case you are not, let me go over yoru statement step by step:
1) There is no such thing as "fiat bubble". There is inflation and inflationary expectation, but it is not the same as a bubble. Noone is buying fiat in hope it increase in value (this is what defines bubble) - you cannot even define what "buying fiat" means
2) Indeed, smart people buy land and other solid assets (like stocks), not park their money in simply holding the fiat currency (money are not supposed to be parked in currency). However, bitcoin is not a "solid asset" by any means - it is a speculative financial asset with zero fundamental value.
3) There is no such thong as "investing in fiat-based assets" you can invest only in financial assets or commodities, and fiat is neither of them. You can, however invest in risk-free securities (like bonds which you may call "fiat-based assets"), but since the major players on that market is the central bank wo can change the bond price by changing the interest rate and who buys/sells for reasons different from profit maximization, the bond yield is too low now (relative to the market equilibrium yield). So, at this time, no rational person should invest in bonds or have money in cash-like assets for anything other than precautionary savings.
You like to play with words and combing them into phrases that have no meaning.
