As a matter of fact, bitcoin doesn't need their platforms anymore to be traded, most Central banks were hostile to bitcoin activities, as they introduced so many restrictions and unnecessary monitoring of people activities, as of today we have plethora of exchanges both centralized and decentralize you could easily have your bitcoin activities without stress.
I don't understand the way some Bitcoin enthusiasts have been romancing politicians trying to make Bitcoin be their first option but what they don't know is the politicians they are seeing doesn't even control the economy, the wealthy people are the ones that control it and they don't even talk much, the politicians will only do small period of time, by the time they are done they get replaced and the circle continues while the caucus rule the economy from behind.
No matter how Bitcoin is pushed to central banks, they will not put Bitcoin first, the idea about reserve was a scam to get the attention of the people here to participate in the election, make Trump win and then change mouth. Why didn't they say they were not going to use tax payers money to buy Bitcoin from the beginning, now that they are in office, they are now killing the promises they made to the public, bunch of liars playing on Bitcoin community.
