270 mill is 18% of the total coin right now. This could definitely crash the market if it was dumped. I wouldn't be surprised if it wasn't slowly dumped. No transparency whatsoever with the premined. The commuity can support this coiin all they want, it is a tough pill to swollow when there's no transparency regarding the premine. But let's all just assume it wasn't dumped, am I right? Bottom line, people are wary to support a coin with premines. It is pretty evident in this case. I guess I'll take my EAC down along with the sinking "flagship." No point In selling now.
Your point is entirely valid, but I do want to point out that this argument has been made since the very beginning. Over time, that percentage has just continued to shrink, and will continue to do so as new coins are introduced to the market.
Could a complete dump ruin it? Quite possibly. But being that we're going through our second 5x cycle and have been through quite a few 2x cycles without much of a hitch, I'd say it's not doing too bad, considering the amount of miners we had latch on to dump.
