I have crypto but no way would I put my LIFE'S SAVINGS in it.I started in crypto in 2011 and even back then I never kept my crypto in an exchange. Too many people getting fleeced even back then with Mount Gox, Cryptsy, etc. when people ran away with people's crypto.
People still haven't learned even from back then.
As you said, cold/harware wallet is my storage location. I have minimal amount on exchanges.
