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.
The bounty program on this forum on average does not use escrow to pay for bounty hunters when the ICO project ends. The token will be distributed by the ICO developer so that the campign bounty manager just counts the number of tokens that must be sent by the developer to the participant. Unless an ICO project has a signature campaign and is paid with BTC instead of a token, there are several and almost all projects need escrow to pay for each participant.
