Do you really think that Binance goes public, even if it goes in which country as it is registered in Seychelles and from the countries they got legal notification all they did was to shut their offices and migrate to another country and with that being their modus operandi what should we expect from him. I do not think they will comply to regulators as they will be forced to audit all their transactions and they wont be willing to do so 
.
I would assume that one day they could move to somewhere else, after all they are starting offices in many parts of the world and I do not see it as impossible. Of course there will be a lot of regulations and with that there will be a lot of limitations on what you can do in Binance, however that doesn't mean it is impossible.. I imagine them starting a big headquarters type of deal in a bigger nation one day because there are lax laws on crypto, and they will be able to make so much more money because being a legit company based on somewhere and even being public means that they will be doing a lot better. They could also sell only like 10-20% of their stocks if they want to on IPO, they do not have to give away all of the company, and with that money they will literally have enough to buy coinbase, can you imagine if Binance bought Coinbase as a whole? It is possible if Binance decides to go public.
