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.
Of course. There should be a programming to place who pays with whichever currency accordingly. It's much better to state payment in different currencies and not just Eth.
Accepted payments for token sale should be limited, all coins are competitive so they just need to use which is the top Currency such as eth and btc how they accept others. They have own coin to promote. And how could they accept multiple coin if it just a problem to use in transaction. They just need few but large in quantity
How do you mean they need few but large in quantity? That's kinda confusing.
