DIY crypto wallets should become the norm (or at least more popular)

Recently people have started realising the problems with proprietary cold wallets, it seems like the perfect time for Free and Open Source DIY crypto wallets to take their place. We (and by "we" I mean you guys which insisted that these wallets were a must-have) have become so reliant on closed-source, proprietary technology to hold our money. It's not as bad as banking, but I can definitely see some similarities.

Making your own crypto wallet is definitely doable, and should naturally be more safe if it uses Open Source software, just like cryptocurrencies do.

Crypto should be about control of your own money. What's the point of controlling your own money if someone else controls your wallet?
