Something recent news that backs up your article:
The biggest heist in history, not just crypto if I'm not mistaken.
By keeping your crypto in your own wallet, that is closer to cold storage than Coincheck was using, which is a shame, but just plain stupid on their part.
I just wish there was a one stop shop for full node wallets. At least some kind of combination, BTC, LTC, ETH maybe?
Also, if the wallet software had it's own open bizzaresque exchange within the wallet itself, maybe using atomic swaps? That would be pretty dope. Quite literally as well I'm sure. Thanks for sharing, cheers!
