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 projects compensated their hunters with the same crypto of the project. Personally, I am good to receive btc, eth or any popular crypto in the marker right now because it will be easier to find an exchanger for it. IEO boomed also because the crypto itself is available in the exchanger that investors took more interest on it compared to ICOs.
