do you mean that one? https://coinmarketcap.com/currencies/x-cash/ so it's like they invested 100,000 USD ( total cap ), and now it's 9,000,000 USD ? So, if they hold 50% now their 100,000 USD turned into 4,500,000 USD?
Is not investment!
The fund was based on $ not their token, they have their own allocation token team they used 100,000$ for different things like a development project. So, you are miss understanding about self-fund.
