Labcoin will be mining with their chips in less than 2 weeks, while ActM lives off the promise off 28nm chips that will most likey not be hashing any earlier than december. I tip my hat to anyone with so much patience, but if you want to see success soon, you'll go with LC.
Those chips will be generating dust as soon as the big 28nm players come to the market. Don't get me wrong, people are entitled to jump on quick money, but I'm in ActM for the long haul.
Do you think ActM's share price is going to increase significantly in the next 2 weeks? Labcoin's will. If you sold your ActM shares now, bought Labcoin shares, sold them 2 weeks from now, then bought ActM shares, you'd end up with at least 2x as many ActM shares.
That's a big gamble, if Labcoin doesn't and ActM goes back up after some news leaks then you are down shares. Not only that but there's honestly not THAT many shares being sold so you'd have to pay a premium to acquire a decent amount of share back.
This is why I won't play that game. You are one announcement from being buried with a bag in your hand. For all we know Ken is getting permission to share where in development the FastHash is. That ONE announcement would change the whole mining landscape, possibly to the great detriment of Labcoin.
