That's a good question, why would you? The answer is simple, because each XPW token has exponential growth in hashpower and will return more and more ETHEREUM month after month, paid DIRECT to your Wallet.
From the moment your XPW is delivered to your Metamask or MyEtherWallet, it joins the XPW Hashpower pool and twice a week, 100% PROFIT is distributed by 30% into purchase of more Equipment or adding more Capital to the Trading Account depending on the profitability at that moment, and 70% distributed between the holders of XPW direct to Wallet via XPW Smart Contract. This dynamic approach insures long term profitability and the Token holder receives up to 4% per week.
That's what XPW is, it's a Cloud Mining Contract that represents a % of hashing power that increases over time. Right now it is 1 XPW = 5 MH/s but in time that same XPW will = 6, then 7, then 8 onwards of hashing power as the pool grows because of the repurchase rule.
But that's not all! XPW is a saleable asset and is already listed on PolarisDEX but you won't buy it cheaper than in Powerhouse Network. Important to remember, XPW is both Decentralized and returns a Passive Income!
