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 testnet 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, so that anyone can play with it as much as they want. Or are we "testing" what will happen when block rewards end altogether? The risk of someone asking money for testnet coins is getting higher

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 could be even cheaper than mining the "old" testnet.
50 000 sats by claim I think it's the same amount you could earn on "mainnet" faucets few years ago
