People we are all arguing that 80-90% of projects are scam startups. But in order to avoid it, we just need to invest only in ICOs, which use Escrow. That's it.
No product progress = no money.
Escrows are rarely used by ICO's and could still lead to lose of funds if the escrow decides to take off to bahamas.

There are still good ICO's out there with good viable working products already. You just need to search thoroughly.
