Best way to buy / trade RVN.

I currently use Trust Wallet and have a very small amount of BTC and ETH. I would like to get some RVN.

I think mining is a bit passed my pay grade…but would be open to learning more.

Based on your experience what's the cleanest way to acquire RVN?

In a perfect world I would like to trade for ETH/BTC but can spend a bit of fiat.
