That's a fair point, but you have to remember that in 2014 things were a bit different:
- The price of Bitcoin was $400 mostly during 2014, a price that no one can even dream about now in 2020
- There was no regulation and Bitcoin was fairly something new that wasn't adopted by many
- The key feature we referred to is regulation
Yes, technically Binance or Crypto.com can always shut down their doors, claim there was a hack and run away with a lot of funds to some forsaken island... but Crypto in 2020 is not the same Crypto in 2014.
Nowadays there are lots of regulations in place, Crypto is not as anonymous as it used to be, and it would be quite easy to trail where the money is going in case it would be stolen by the exchange itself.
Small exchanges might do that, they have small volumes so they can always screw their investors (Bittrex for example) but with ever increasing regulation it's hard to see Binance facing the same faith Mt. Gox faced in 2014...
It's like in 2008 Washington Mutual in the US disappeared ... it was bailed out by Chase but if you google search the word "WAMU" you would find a radio station ... back in 2008 things were different than they are today....
It doesn't mean things can't go wrong, but imagine Google's CEOs running away with the company's funds and leaving Google to shatter to pieces - if this is unlikable then probably the same can be said about Binance.
Most businesses want to stay and continue trading for a long term, as they earn fees from so many trades - security is definitely an issue but what we know now in 2020 is not the same things we knew back then in 2014 .... Bitcoin in 2014 was not the same as it is now ...
You could also try to compare it to MySpace ... Facebook managed to succeed, MySpace didn't ... likewise Mt. Gox - it's a shame that so many lost their funds back then in 2014, and it's a shame MySpace couldn't become a successful business like Facebook - but you can only see things now ... go back 5-6 years and you wouldn't be able to see and learn what we already know by now.
Again if anything is to be concerned of with big exchanges - is mainly regulation. Regulation is definitely a reason to be concerned over a security breach.
