It seems that not a day goes by without another central bank jumping on the crypto train.
it depends on what this "crypto train" means.
so far what i have seen is that whoever jumps on board (specially when it is a bank) they are trying to develop their own centralized shitcoin. so there really isn't anything remotely interesting going on with their "jump on board" and definitely it has nothing to do with bitcoin.
this is the situation for now and will remain like this for a couple of more years. then as these centralized shitcoins fail one after another, all the while bitcoin keeps growing, they end up jumping back on bitcoin train...
