Bitcoin is already legal in lots of countries. If you check Wikipedia you’re going to see that there are lots of countries there that are marked as countries where Bitcoin is legal, and there are places also marked as where it is illegal. So, it’s already legal in lots of countries,
Yes, some countries have legalized Bitcoin but they didn't legalize it as legal tender and this is what makes El Salvador different from all the countries that have legalized Bitcoin.
To me, the Ukraine and Greece government seems not to be serious about the issue of Bitcoin legalization because they have been on this talk for a long time before El Salvador think of using Bitcoin as legal tender and if this continues they may not legalize Bitcoin while they continue talking about it every year.
Finally, Ukraine ends up legalizing bitcoin and that's only the important thing. Hopefully, the next big step will be adopting bitcoin as a legal tender just like what El Salvador has did. This is a very positive news in the crypto market and if by chance they will start adopting bitcoin too as a local currency then this news might bring bitcoin closer to its new ATH.
Despite of some negative news that come out like banning bitcoin in some countries, there are still countries who chose to be positive on bitcoin. And by simply believing bitcoin, this will create surely in the later part more positive and amazing news that will give credit to the crypto market.
