Honestly there is no pattern or activity that can help a person to identify a scam ICO. Usually high profit claims, bad business model and poor developers are the signs of scam ICO.

There many ICOs in the market this year so if the ICO is good and legit and also follows the regulations of the exchanges it will be added. I do not think there is an alternative for that.

That is not a current news, and it is not a big issue too just a upgrade got delayed. It is nothing to worry about.

Bitcoin: The End of Money As We Know It is one of the best documentary video out there. It is also advised to search in google for documentaries regarding bitcoin or crypto.

There was a very low dip last year too. It is adviced to keep patience in this regard as anything might happen within a short period of time.
