Binance is first and foremost an altcoin exchange and has very little to do with bitcoin. and the day they shut down is going to be the repetition of dozens of other bigger exchanges shutting down in the past and won't affect bitcoin.
You said "and the day they shut down" - so in your opinion it's only a matter of time before they shut down or there is a chance their business can last for years and years from now on?
How do you see their chances of staying in the market?
