The big "problem" is that the coinbase reward on the testnet is low (0.39 tBTC + fees) and the hashrate on the test network is high. Basically, most tBTC has already been mined,
I do really hope people will return the tBTC, like i said above: tBTC is worthless, but that doesn't make it easy to come by, so the more worthless tBTC is returned, the more people i can help.
Wow. I didn't know the block reward was already THAT low in testnet

Do you have an address for donating extra coins? I should have a little less than 4 coins somewhere.
Testnet coins being hard to get defeats the whole purpose of testnet. Don't you think it would be a good time to reset the whole testnet (or just start a new one on a side), so that anyone can play with it as much as they want. Or are we "testing" what will happen when block rewards end altogether?
What would be needed to start a new testnet and make it public? Just one machine mining it and keeping it alive? And a faucet for the coins. And maybe a block explorer for it.
Running a new testnet and a faucet would be cheaper than mining the "old" testnet.
I don't thing anyone would have any reason to oppose having a sizeable pre-mine for the faucet, say 1M coins. (since they are worthless)
