1. Complexity - Is It Just Me, or Is It Still Too Hard?
Bitcoin is complex; I think most of us will agree on that. Complexity has been reduced with new standards and protocols, a magical threshold of simplicity is unlikely without trusting a third party.
Bitcoin is not complex if you only buy bitcoin, store it in a self custody wallet and make transactions from your wallet.
It is easy enough to use it well without mistakes. It does not requires too much in storage if you use SPV wallet software like Electrum wallet.
Just use self custody wallets and if they are open source, you are doing good practice.
