Well I've been in for 15k AMBER for the last few weeks. I remain to see whether once all final company owned shares are sold there's a dump in a few months and I joined at just the wrong time but I'll remain optimistic now for and hope to get at least one quarter of dividends out.
One thing I wanted to check is whether anybody else had got AMBER working on a testnet or if there isn't one working with this coin? I've had some issues and for a project I'm currently working on don't want to burn real AMBER unless I have to.
All company shares will not be sold as Ambercoin as the company is planning on having a traditional IPO and issuing traditional stocks in the future. Even still, the fact that the numbers of coins for each round are decreasing at the same time that the price for each round is increasing means you won't see all Ambercoins sell out for a long long time.
As far as dumping, as long as profits each quarter continue to increase along with a steady rise in the price of the coin why in the world would anyone dump?
