Bitcoin As Legal Tender?
Allowing the use of bitcoin in a certain country does not mean that bitcoin is legal nor does it mean that bitcoin is illegal. Most countries in the world have allowed their citizens to use bitcoin
As there are few countries that have put BTC as legal tender?
yes, the reason why most countries in the world have not made laws about bitcoin is due to many bureaucratic issues and because they still want to observe more how far bitcoin will come, when countries like the USA make laws about bitcoin, then the rest of the Countries will also make laws about bitcoin, but with bitcoin it is accepted in the US and US financial regulators collect bitcoin, so I think politicians will not make laws about bitcoin. will leave things as they are
What does this mean for the system?
I confess that you don't understand the question, what system are you talking about?
Does this make BTC more centralized?
no. bitcoin remains decentralized
Is making BTC legal tender a benefit?
Of course, think that with clear laws a company could pay salaries with bitcoin and the pension system could deduct the value in bitcoin, people could pay water, electricity, TV and internet bills using bitcoin, that's why it is necessary to have laws clear about bitcoin. This does not make bitcoin centralized
If say all the countries in the world did this? Could BTC be more controlled and centralized?
people get confused. bitcoin will not be controlled and centralized; What is controlled and centralized are private things that belong to people, I'm talking about things like exchanges, bitcoin ATM, banks, wallets. as they are private property and that in the real world they would be regulated, so also on the internet it doesn't change anything the fact that governments can regulate this. but bitcoin itself will not be centralized
Is making it Legal Tender just a way to offer acceptance. As a way for the government to seem friendly and let the people have better access to their own financial means?
governments regulate everything. So they're not seeming friendly, they're simply doing their job
