Where are Modern UI Crypto Exchanges?

I write this at a frustrating time in my life. I “see” the future of a lot of promising altcoins (BAT, NEO, SIA to name a few) but lack the courage necessary to use exchanges like Kraken or Bittrex. I use Coinbase for one simple reason. It is easy to figure out. I give Coinbase $USD. They give me crypto. That’s all there is to it.
Changelly is similarly easy to use. However, you need wallets for each and every crypto you purchase. That’s a big headache especially if you have enough difficulty remembering your normal passwords.
What if there was a exchange with a modern easy-to-use UI that was relatively trustworthy (like Coinbase) but had a diverse amount of cryptos to choose from, and the wallets to hold them? It would need offline wallet options with private keys, of course.
I point out Robinhood as the Stock Exchange version of this miracle. It makes trading stocks about as scary as petting a bunny. The UI is so easy to use. Where is that for Crypto?
Not here yet.
I wish we had the cryptocurrency version of Robinhood. I would gladly support the ICO of such a program.
