Clearly its just a study but nothing assured us about such ideas,binance is indeed a good exchange but there are other good exchanges that exist for long and proven to be more functional and accurate,..
Though it is just a study, if OP is religiously gathered those data it eventually reflecting the possible result that using Binance exchange will build a good profit than of the other. If we analyze the data, it is proven.
i am sure binance had lost many investors since thats a serious hacking involving millions of dollars
Not really give a huge effect on the market and I doubt that investors will leave Binance because of these issues. They are protecting their reputation and so the will immediately address the problem and take action for the resolution of it.
I think yeah there is an edge to the Binance users in making money as compared to those on other exchanges. It is because this is the best exchange and has more than 90% of the crypto users which makes trading on the exchange a bit easy and less time consuming. The exchange provides extra security which makes it possible to take away the money you make without loosing it to hacks.
