Those "IPOs" are idiotic. AMHash isn't selling shares in some company. They're supposed to be selling hashing power yet had no shares up for a good few days and the price went above IPO price. So AMHash could have sold more shares but didn't. To limit the amount of time those shares are available to purchase is simply lunacy, they need to be available to purchase round the clock.
And they need to be promoted too. I've seen fuck all in that regards except unofficial promotion by shareholders.
Are you and I the only two that have been scratching our heads over how this has been handled? Where is the value in staggering these mining contract offerings out over weeks and possibly months? If there is 25PH to sell off today, why not offer it all at once instead of leaving batches of PH off the market for weeks on end as the network grows? (albeit at a slower rate these days). The only way this makes any sense to me is if the other 20PH that is slated to be offered in contracts is already being used for self-mining, where it is a simple matter of changing ownership of the GH's on paper and sending the dividends to the owner of the GH's. And even in this case, I still do not see the value in staggering the release of the PH.
You can self-mine with it until you have offloaded the chips via shares of GH's to someone else and let it be, pocket the BTC and move on. I could be missing some key pieces of Fried Cat's strategy here so feel free to fill in some blanks. It is tough to know for sure given AM's recent history of blunders if this is a mistake or a well thought out decision by the company. Gives people something to discuss at least, there isn't much else going in for a while.
