Another Bitcoin? Why are there a lot of them? What is unique of this Bitcoin?
Because all XS coins are forks of basic cryptocurrencies. All XS coins are backed by BTC, LTC, ETH etc. it's about the name.
All XS coins are reserve coins and they have real cost. 75% of ICO fees create a coin reserve fund, thus related to the actual cost.
And the main Plus - all XS coins are can be mined by all versions ASICs also by outdated equipment.
I do not quite understand how this will be implemented.
It's quite simple. 75% of money that project get during ICO go to Reserve fund of BXS. So these money are the "gold reserve" of BXS. ex. : coin supply is 1 000 000, they sold at 2.18$ each coin, so total sum that we get - 2180000$, 75% is 1635000$, so actual price each coin will start at exchanges - 1.635$/1 BXS. This reserve will be used to stable prices at exchanges during trading, so all investors will not depend on BTC/ETH prices, these coins are safe and we will not see the same situation like with Bitcoin this year. All XS coins are the payment resources at Bilisef platform for startups and ICOs. Every membership have some price in XS coins, every research at platform have some price in XS coins, so every startup owner will buy or mine XS coins to get this membership. Membeship price for startups will grow every month (some %), so the XS coins price will grow also. 28.11 we started developing EPayment system for XS coins and we suppose it will be very interesting for all crypto community members, because Bitcoin, Litecoin, ETH and other basic cryptocurrencies we see as money storage only, XS coins as payment instruments.
