I really like Waves because its actually got a feature live right now that is working and useful - the exchange.
Near zero transactions, I can send my BTC or ETH onto it and trade on there quicker than any other exchange and I can withdraw it whenever I want with no limits etc.
Add to that the stream of good news coming on Waves and Im really positive about its future.
I have about 10% of my stack in Waves, im considering selling more of my ETH to increase that.
