I have made a proof of concept that works on Ropsten Test Network. Now for users to use it I need a large number of Test Ethers in my account. As far as I know, we can get only one ether with one IP in a day. I need thousands of ethers. How can I get those? Please help. Its urgent.
You can set the gas price to almost 0 and it'll still go through quickly on Ropsten - because Ropsten blocks are usually not filled. You may be able to simulate main net gas usage by scaling everything (incl. gas price) down by a factor of 10 or even 100. Mainnet is charging ~10Gwei for a reasonably fast transaction now. On Ropsten you can easily do with 0.1Gwei.
If you still need a few thousand Ropsten Ether, you can contact me at firstname.lastname@example.org - I can sell you some for non-test Ether.
