I am sure there are some that can still be worth your time but those numbers keep falling drastically. If you take a look at the graph that akamit posted above you can see that there are less and less ICO campaigns on this forum.

I am not active in the altcoin world but one thing that could have an effect is if the bounty hunters agree not to partake in bounties that don't pay in either ETH, BTC or a stable coin. The less people take part in them the less advertisement and visibility they will receive and it will not be worth their time.
