I mean the scrypt hashrate of DGB.
Thats what he means... for approx. 0.4 btc per GH/day you can rent Scrypt hash from NiceHash/Westhash... and point it at wherever you want...
But this is not the DGB network hashrate, I think.
It's generic Scrypt hashrate available for whatever you want. When you rent it and point it at a DGB pool it becomes DGB network hashrate....
Perhaps I am misunderstanding your question?
