Not to be a downer but:
"At this time, we don’t allow transfers of your existing cryptocurrency assets into your Robinhood Crypto account. There are a few reasons for this, but our primary concern is to prevent money from illegal activity being used for transactions on Robinhood Crypto.

We’re currently building specific anti-money laundering measures on our platform in order to protect both our platform and our users. We’ll be sure to update you if and when this type of transfer becomes available."

Found that on their website. I'm very happy about this news don't get me wrong, but it will take about a year in order to use it like coinbase. A few months to get every state included and then at least a few months to make "specific anti-money laundering measures".

I guess what I'm saying is this is great news for 2019.
