What will it take to make bring crypto a mainstream asset class?

I mean, things like ease of use, accessibility, safety, and reputation. Recently I've also considered stability something the crypto space needs in order to compete with fiat.

I've been on the fence about crypto for a while and recently dipped a toe in. I find it incredibly daunting, and even made a moronic mistake that had one wallet ransacked. The learning curve is just a little too steep, especially if you want to use a non-mainstream exchange.

So, honestly, what do you think it will take to bring crypto to the general populace? What's your expected timframe for mass adoption? Do any coins currently meet those requirements?
