For me, the best site for best ICO's are here in bitcointalk. All you have to do is browse the long list of ANN's and choose.

I think Ethereum hitting 10k is very much possible, but it wouldn't get there this year. It could take two years to get there. I believe only Ethereum has the potential to get there, no other coins can get there.

Bitcointalk is the best place to find new ico's. you can also use ico alert and tokenmarket
