Well, according to your post, you also included the Hardware Wallet to being "not safe". Which would you recommend ?
I mean, I don´t see Paper Wallet being much better, except if you have a bank vault, where you place your paper wallet into, and that you can access only 8-10 daily hours on business days, not in the middle of the night when you think you might wanna access your 20 BTC because some coin is dropping.
