Cold Storage – barrier for too many people interested in Crypto?

I've been thinking about this. Cold Storage and moving your coins around on/off exchanges/wallets/cold storage can be confusing/stressful to many interested new investors. I understand that if you're interested in Crypto then you've likely already done this research and are willing to get over this learning curve.

But if Crypto is to be adopted by the rest of the world, then how does the entire world get over this learning curve and barrier to entry, other than the barrier being lowered a bit. What could possibly do this? We still need cold storage and hot wallets, but in your opinion, what could be done to change this?

How can the barrier to entry be lowered, without security being compromised, and retaining custody over your own keys and coins? Will there be new forms of hardware wallets?
