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.
It can help the ICO to reach the soft cap at least and it's a good idea actually but only a few like to implement this idea maybe because they want to simplify things they can easily calculate the crowdfunding if they accept the top two coins in the market only and they knew that majority of investors and traders had the top two coins in the market.
