Yes you can lose all you money hence you should not invest anything at all. That brings me to another question - What are you doing here anyway?

You have to take some risks in order to reap rewards. If you are one of those people who thinks that people who come from a lower strata background are unable to run a business then you will suffer in this sector. Current valuation of Binance is very high and chances of it getting hacked are the biggest because hackers target biggest sources most of the time. But the company is not sitting on it, obviously they have a team keeping hackers at bay.

You connection with an exchange is only for buying and selling your coins there. Unless you are into buying BNB tokens and then the background research makes sense. In which case I will not comment because I am not a fan of exchange tokens but they seem to have performed well in terms of price.
