OP mixed the "central bank" as an unique one (it doesn’t exists, although MFI could be representative for the west) and the multiple national ones (FED for the US). They arguments doesn’t hold as the national ones creates money and the are much more numerous and diverse in interest around the world than the ~5 bitcoin pools mentioned ahead.
The FED is quite powerful and US strongly influence many other banks but that’s by situation, not by design.
evem tho unique starts with a vowel, we say a unique, not an unique, I guess because it's pronounced like "younique", long u. Short u would still be an tho. As in, "An understanding"
the "does" in "doesn't" absorbs subject-verb the conjugation, does is now the verb that needs to agree with the subject, it. Exists returns to it's infinitive (unconjugated) form, exist.
"They arguments doesn’t hold" typo they ought to be the, those or their, not sure what you meant. Since arguments is plural you want don't, not doesn't, alternately "the argument [singular] doesn't hold"
'national ones creates money' subject verb agreement again, either one creates or ones create
"and the are" s/the/they
"bitcoin pools mentioned ahead": ahead doesn't quite apply to comment threads, like on a road you have cars in front (ahead) and in back (behind), but with comments it's above and below, because you scroll up and down, not forward and backward. You could also say aforementioned referring to something mentioned earlier.
