And finally: Don't forget Electra (ECA)! It's also a privatecoin and it's marketcap is very low. So there is huge profit in the air.
I'm already invested in XSPEC and I've found that it's given me sizable gains, gotta love their community as well. JBG, their lead developer actually takes the time to answer everyone's questions.
I really like the concept of Waves, I think I may buy some soon. What is appealing about Electra? They have a great website, but not too much information about their tech.
