Some people saying BTC has no value as is made from nothing. Those same people using money in every day life. If we look into paper money as terms of value this piece of paper is also without value and also made from nothing.
If we think this way then we should be only exchanging goods like gold, stones, weapons, food.
BTC, Crypto is in my opinion only next step in term of money. So we will be calling BTC money soon. It will only be huge advantage for us early adopters to get some while cheap.
When btc will be replacing money in terms of salary anyone who will one 1 BTC only will benefit a lot as with price increasing people will get salary of cca. 2000 sats and 1 l of milk will cost 1 sat in the store.
Try google'ing the term "legal tender" so you can have an idea about "paper money". One of the reason why we use paper or coins is because using good like gold, stones, weapons, food is as term of exchange is problematic.
You're correct, BTC or crypto in general is one of the next step for "exchange". One of its advantage is the ease of use of crypto, compared to fiat. This is the same concept why we don't normally trade goods for goods.
