Better control over the funds and convenience to use, these indeed are important benefits that bitcoin is able to bring.
Quality control of the funds is in any case well, but perhaps I did not fully understand this kitchen. After what happened with the exchange Bitfinex, I was even a little afraid to buy bitcoin. The cost of the big and the risks even more.
You should not have any issue in buying them even after the bitfinex hack unless you have not lost your coins there, as people who have suffered losses will prefer to stay away from bitcoins for some time.
