If someone makes an erc20 token, does ethereum profit from it? Do they get a portion of revenue? Thanks
It doesn't make any direct profit from it's tokens, but since being a platform for investments is their main utility right now, I would say ethereum has a lot to gain on it's tokens success. As ICOs get more popular, and if good companies end up emerging from ether platform, more people will buy into ether, in order to be able to invest in these ICOs, so it's price will be rising. Also, as soon as ether moves to being proof of stake, it will be even more common for investors to hold to Ether, since they will be making profit from holding their investments funds, and then could be having profit from investing in ICOs, so if they make good decisions they will always have some profit, and this will be a great incentive to ether and use it as an investment platform.
