I am wondering some ICO's accept only ETH. Some accepts BTC, ETH, LTC and other cryptocurrencies as well. Does accepting more currencies in ICO plays a roles in its success.
Also Ethereum's smart contract are built for accepting only ETH. How other ICO's are accepting multiple cryptocurrencies and pays tokens accordingly? Do they have to maintain a sheet of who pays in what currencies in a sheet and allocate tokens accordingly. It seems to be a hard manual process.
In order to make their platform diversified, they will also need to make their investment tool diverse in such a way that, different investors that prefer different cryptocurrency can have much flexibility to invest on their platform. In that case, reaching their softcap and even hardcap would be even more possible. Still, I guess in the end they will convert it in a single currency.
