I like your picks with the exception of Tron and Reddit. Tron has too much hype and nothing tangible. Reddcoin seems nice, i don't like the supply. I would replace those two for ADA Cardano, I love cardano and believe it has very long term potential for huge gains, the wallet is amazing and fast, the development team is awesome, and the debit card project will take it to another level. I love your Modum pick! Just some inside on my thoughts.
