I only fire up my rigs now a days to solo mine a new coin if I catch it at the very beginning of its launch. Usually get a few good blocks before the mad hash power of rented rigs pours in.
I never bag hold pure shit coins like the ones OP mentioned but if the coin is showing swing play action I will hold a bag and sell some off on each rise.
I never gave this coin a second look but seeing all this activity has perked my interest. More than likely missed the action already but wow what a nice amount of movement.
My twitter feed just blew up with retweets from the devs last tweet. I got a good feeling here. Even Ccex retweeted it and I dont see them retweet anyone. I'll buy some.
My twitter feed went nuts too. Someone is working hard on this coin. I'm in.
I don't know if it's related but it has the name Grid in it and I made real good btc on the other "Grid" coin. Can't wait to see what the dev cooks up!
