Trevon gave up on steem a while back and only recently got back in after the price of steem went up.. Dunno who Nick is, but.. I think Trevon just realized he messed up earlier and that steem is more solid than he thought it was.
I don't really know much about him myself so I won't comment on his character, though.. I personally kind of see it as a positive thing that he wasn't aware enough before to see the value of steem and now that it's been growing so much he's jumping back on board. TO me, that seems like a good thing. Hopefully it is, heh.
