If Bitcoin hits 80.9 trillion dollar this means 1 bitcoin = $38,523,809.52
This means every owner of bitcoin will be a multi-millionaire and well the transaction fee would be $30819.05 @ 0.0008 BTC transaction fee great for coin that is introduced as small to nothing transaction fee
. Well why would I care for $30k fee if I have multimillion dollar in my stash. Definitely I will change this to fiat currency since moving it to fiat currency, I can save a lot in terms of transaction fee every time I move my money.
The transaction fee at those rates would kill bitcoins price before it could ever reach that high. What you don't realize is that as bitcoin has increased in value the number of people holding bitcoin has also increased but the average wallet size has shrunk. If your life savings are worth 10k USD you aren't going to have much use if it costs 30k USD to send it to someone
It is dubious that the price will ever get there (with or without fees)
But just like the transaction fees are going to kill Bitcoin halfway, the transaction fees themselves will likely be made entirely irrelevant for the transactions of these "small" amounts before they get to the point of killing Bitcoin. Indeed, if you are going to transfer a few hundred million dollars of Bitcoin, such fees may still be "not high" (in relative terms, of course), but a lot of ways will undoubtedly emerge to transact with bitcoins without using the blockchain (i.e. without having to pay insane fees). It is just a matter of time and price itself, and I'm not sure about the former
