Op the person that pay the house rent Bitcoin is more knowledgeable on Bitcoin than you. What is the core meaning and the creation of Bitcoin. It is a peer to peer digital currency which is meant to buy and pay things online so what the person is on the confined of the creation of Bitcoin and not out of point. Yes Bitcoin is better than the fiat currency but if the receiver of the transaction agree to receive with cryptocurrency then and if the sender has it then he can send it to the receiver because there are sometimes the transaction process is cumbersome, the process is long and delayed so to make it faster the sender will just send it directly to the person address without using third party.
Argentina is cryptocurrency friendly Nation so a large number of people are using Bitcoin so it is easy to pay with bitcoin than Bitcoin.
In this kind of decision, it relies on the user and receiver of the btc transaction.
If they feel they are doing this for convenience purposes, then, for me, there's nothing with it.
So long you know what you are doing and you feel you are taking advantage of the features of btc transaction, are all that matters.
A lot of people feel it is being wasted because of the potential to gain profit in the market, however, it is on you if you will utilize
btc to other valuable purposes like paying for something that you need or want, and you are happy about it.
In this case i quite agree with what you said because in the end of course your decision is in the hands of everyone and as long as both parties (those who pay and those who are paid) are not bothered by what they do where bitcoin as an alternative to payment then why not because after all things like this in the end there must have been a joint decision first as a form of agreement. so, that in the end whether to use bitcoin or not it depends on the agreement.
As long as we do not feel burdened or indeed as long as it is still profitable then why not because in the end things like that depend on the perceptions we do.
