As many others have said, I would not put all the money in the crypto world, why not split it 50/50 or whatever suits your risk willingness.
A note on the exchanges: In the end, I would use different exchanges, so if one gets hacked you will not lose everything.

Beside this the most important point IMO is: transfer the money to your private wallet and store it in a paperwallet or a hardware wallet like the Nano ledger. It will cost you a bit for each transaction but once your money is stored on something not connected to the internet you won't get hacked anymore
