Yes..however I only keep a very small amount on any of these hardware wallets. I believe any decent size amount of bitcoin should be placed in paper wallets
Paper wallets also carry some risks. It takes quite an elaborate setup to be fully safe. And at that point one would also have to consider how to pass on one's crypto holdings to their family in case of unexpected death, which makes a safe setup even trickier. Makes me wonder how many Bitcoins will actually be accessible by the time the last block is mined.
I agree..they can be tricky. That is why when I started in crypto I took the right steps which I outlined on my website on how to create in a very safe way and also test said paper wallets using outside programs other than what created the wallets.

Yes...many bitcoins have been lost. The following shows where we stand at the moment. It says 4 million bitcoins lost forever at the moment. Probably more since nobody really knows
