SC will probably spike soon. I would not hold any SC long term. I have been speculating that it will do something similar to DGB. I day trade STEEM and I seem to be profiting very nicely. STEEM is something to collect more of over time. I would keep STEEM in a portfolio, you can expect STEEM to do very well in the long term. Also expect to see NXC jump a little this week due to a video game being released.
