I've been in and out over the last two years and made about 30% profit during that time. In the last 2 months though I have loaded up on MAE with avg of 80c but all my eggs are in this basket.
Reason I have so much confidence is because I know a couple people one a top ten holder but they have way way more in this puppy than I do. I always hassel them for updates, i think as a top ten they are privy to more "insight" than us.
