What is your mining hashrate? Most of the rig rental sites are free to register but charges a small fee.
really low... 730kh/s (for scrypt)
not worth it then that hashpower is a joke basically a single gpu, i doubt someone will ever consider to rent it for mining
it's better if you use it for instamine some coins if possible, but anyway i would suggest miningrigrentals, they have a top notch customers service
Miningrigrentals is the way to go. Once, found a 50terahash miner on there rated at 1 kilohash, priced for free, I mined for 4 hours, FREE, before the hashrate was cancelled because the rig owner cancelled it. Got 30$ of bitcoins because slushs pool found a crap ton of blocks in a short time. Scrypt is cheap there too, and the prices are good to sell.
Most of their scrypt rigs are small gridseeds, so if you price your gpu low enough you SHOULD get rentals in a snap.
