Here's my take on the 777's
There are many penny stock traders that are not on ihub, or any other forum (of course) They trade privately in large amounts, and have "connections" for sure.
When these 777's come up, it is a sign that it is "safe" to buy in. That the MM's are no longer going to manipulate the PPS, and no more dilution will occur.
Once these large buyers get the sign that it's safe to buy in, they will do so. But not in huge 500 million blocks, for obvious reasons.
Now I've heard that there are L2 signs before the 777's hit, and that some buyers can take advantage of those as well.
It's all a game at this level, the more you know, the better off you are.
