I am holding my BAT, this is a good project and besides, they have Brave browser which they can incorporate their token later on etc. I am optimistic with the devs and confident enough they can deliver.
bAT has too much hype up front I would be careful with overhyped projects - but yeah I think BAT can be amazing long term - Another big coin long term is NeO it can be Chinese Ethereum.
Anyways, the best sources of information are usually various trading slacks, reddit, bitcointalk and various YouTube channels. Once you are involved in the community you will know about IcOs easily
