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.
Some ICO accepting other cryptocurrency than ETH, such Bitcoin, even fiat currency.
Usually they will using dashboard in their platform, so you must register first before contributing.
And they will create some cryptocurrency wallet in your dashboard account to receive other currency like btc, ltc, trx, etc.
Yes, it is depends on the ICOs you are working with, like many ICOs today are using ERC20 of ETH platform, and because ETH is most popular and most useful for ICOs project, so we easily see it is used to buy ICOs token more than normal, and more cases shown that, a big ICO will also use not just ETH but also many cryptos like BTC and Fiat to buy sell tokens, by this way, we can easily use our money quickly than just trasfer to BTC or ETH or some other altcoins, after all ,ETH and BTC is still the most famous cryptos in the world.
