some time lately, I have seen several projects making payments using ETH. I did not say that new projects will die but they might use this alternative, so my conclusion is whether this will be a new era in 2020 where all projects will make payments using ETH or other coins that are already on the market, or is it just a coincidence that they use this method, to avoid a very drastic decline in value when listing on the market?
the initial appearance of IEO was also ignored but it boomed in mid-2019.
share your opinion, any advice will be apreciate

Some bounty are using Tokpie where bounty hunters can trade their bounty to eth but the price is not good to compare if you are going to wait if the projects get in the exchange, EMIREX whose token is already in the market is now doing a bounty campaign, other than these two there are none and very seldom to see a campaign paying coins that are already in the market.
