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?
Eth is the best altcoin on the market. Using it for any payment anywhere will never damage the power of the project. You can be sure that even lower level projects never think about this competition. They have to use btc, eth, xrp, bch as well as their own tokens for payment. If each new project does what it wants, the statistic of ruining new projects will be further inflated.
