Binance is a great company no doubt, no institution is too big fail. Failing to me is superlative there are areas where they their services are lacking and they need improvement on those places I can attribute them as "fail" if I so wish. However, there has to be a very competitive opponent to shake Binance off Binance off the radar or better still a heavyweight attack on the exchange to pull them off the level they are currently.
But there is merit to that term too big to fail, no doubt about that. If you reach a certain size and you are systemically relevant, chances are good that government will bail you out if you fuck it up because otherwise all your employees are without jobs. Yes, never say never but we have repeatedly seen in the past that the bigger the institution and the more money and workforce involved, the more likely it is that you will be saved with tax money even though you are to blame.
As for Binance, they are actually really huge. Look at the gap between their trading volume and rank two. It is hard to think of a scenario that that gap will be closed anytime soon as their business model is sound and customers are satisfied. This is not a business where customers quickly change the provider. Liquidity is awesome, service is awesome, product offering is awesome. Binance is in a great spot to say the least and probably for a very long time.
My dear friend, you couldn't have said it any better. There will be a lot of damages done to the society if care is not taken for Binance to fail it means a portion of government has failed. The government generallly knows that the existence of an enterprise like Binance is doing to relief them of their own stresses like (Job, creation, sabotaging; crime rates through the establishment of trading to keep jobless people from engaging in such acts, making tax collections a lot more easier).
So, when such scenario plays out, the government will definitely find a way to help the entire Binance management to overcome anything likely going to cut their existence off in the shot period of time, Binance is currently like Google of the Search engines to the crypto world. They constantly update their platform with what will likely draw customers away from them easily.
