I prefer that CMC will be manage by independent organization that are not against nor in side of any currencies out there to maintain the balance of their data. But if CMC will fall to the hands of Binance there is a big chance that the data in CMC will not be that trustworthy compare to what we have seen right now.
Though it is only my opinion because I am not so sure yet what is the big reasons behind the action of Binance in buying the CMC. If this will not affect that much to the freedom of data in crypto world then I have no problem to it as I am also a user of CMC and almost all the data that I need are coming from that site.
