If my understanding is wrong is this a marketplace where you can offer goods inexchange of crypto? What altcoins are listed then?
UBcoin is platform which we can exchange real goods and receive crypto currency. And as i know so far, maybe it is only major crypto currency beside UBCoin tokens.
as far I know Ubcoin has no plan to have their own exchanges from other coins to Ubcoin and you need to convert it first to other exchanges to have your Ubcoin token as this Marketplace platform will only accept Ubcoin token as payments. I'm hoping in the future they will consider this to make it convenient to consumers.
This is an Ubcoin ICO projects , this ico is still promoting their platform ,in selling different goods and will be paid with Ubcoin tokens , in which it can be made in the Ubcoin market, in the market it could only be paid by Ubcoin tokens, to acquire this tokens they are still on ICO token sale, in Ubcoin market no othertokens will be used for those exchanges for that goods.
