Its important to realize that the reason because wallets keep being hacked is because they are part of the old system, and don’t use to be distributed. The blockchain tech itself has never been hacked so far since it came out in 2009.

This is the same for marketplaces like Opensea or Coinbase: they are not decentralized and need to use extraordinary security measures. That’s why they charge extra fees for them.

If you don’t trust yourself to keep track of your key, or you’re afraid somebody will steal it from you, you can have Mr. Gox or Mr. Web-wallet or some other fellow hold your key for you. He’ll let you pick a secret pasword, and he’ll open your safe for you if you tell him the password!.

But make sure if you’re letting some fellow hold your key that you trust him; you have to trust him both to keep your key safe, and to let you use it whenever you want. And never let some government tell him that he can’t give you back your key until you fax him copies of your passport and social security card.
