eSports betting platform Unikrn has raised $15 million in a pre-sale participated by some big name investors, including Mark Cuban.

The Seattle-based company launched its initial coin offering (ICO) pre-sale last Friday for its UnikoinGold tokens, which are exclusive for its skill-based betting platform. The digital currency is designed as a decentralized token on the Ethereum platform, which means that it can be bought, sold and traded on digital currency exchanges that deal with Ethereum.

Friday pre-sale was limited to big blockchain groups, which Unikrn founder Rahul Sood said they “felt would work to build commercial opportunities for the UnikoinGold ecosystem,” according to GeekWire. This was followed by a “crowdsale” on Saturday, and Unikrn said it plans to open the token sale region by region gradually.

Also among those who participated in the ICO were ethereum co-founder Anthony Diiorio, Blockchain Capital and Pantera Capital as well as Draper’s Dragon Fund, a joint venture between Draper Fisher Jurvetson and DragonVenture.
