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.
Yes accepting more currencies on an ICO helps a project but not a lot. People will invest in the project if they see potential on it. However if they see that an ICO is accepting more than 100 currencies and it looks like shady and scammy then its useless. Investors will pick the ICO with a brighter future regardless of the currencies they are accepting in ICO.
