lets say usa dollar and all currencies will be highly devalued .....then how we know the btc value??
most traders use USDT so if something happens with usa dollar is my USDT Will be worthless over night?
If USD will be devalued then obviously the price of Bitcoin will rise but that price is pegged to USD.
The question is that, will all of the establishments accept it?? In order for you to buy things right now and you have Bitcoin, its either you will tell to them that you will buy Bitcoin or you will convert the BTC into USD and you will use it. It will still be the same since the price will go up at that time.
not how I view things in this market. Bitcoin and other cryptos are not tied with the value of fiat currencies unless it is a fiat based crypto just like USDT. Regarding the acceptance of cryptos, there's what happened recently with PayPal wherein it will be accepting cryptos as mode of payment but as from what I have heard, in every crypto transaction of goods or services perhaps, there is a convertion to fiat not really a direct crypto to crypto transaction. So maybe, there will still be years for its total acceptance.
