I think they're the best in crypto right now, but for a mainstream audience they're not all the way there. Being told that if you lose your password, you can lose access to your account and funds is really scary for a lot of people. Securing your account with different keys is very confusing, even though I'd say it's quite a good system technically.

Steem has really changed things, opening up crypto to new creative people who wouldn't have otherwise been involved. So that's nothing short of amazing.
