I like OMG.I think what the guys did is great. OMG is also experiencing a dip at higher level ( reached peak $12 something in September and has not been able to regain it, if you look at graph. If yougo to coinmarketcap you can see that it also experienced a dip). However none of the coins are mooning in one day -which is a sign of something more long term ( if you check ETH and DASH - none of them mooned at the beginning)
Yes. The main indicator for me, post ICO is how is the company using the resources to actually develop the product. Ambrosus has gone full into development and so far, has reached all the deadlines. This for me means more than how much a coin is doing on the exchanges at early stages.
