You definitely should. For the past 4 months, I tried to buy and chose which coins to hold. In the end, BLX had outperformed me by about 25%. I sold most of my ETH and BTC and decided to buy on Ether Delta. It the only crypto fund at the moment and it is a great fund. I highly recommended.

However, Iconomi will not sell BLX to US Citizens. If you are a U.S Citizen, you will need to buy on Ether Delta or any other exchange.
