There are a lot of crypto scams happening nowadays, and this testnet bitcoin can be used to scam others who are not aware that it's a testnet BTC that can't be used for anything and can't also be traded.
 
I have come across such a scam before where I saw someone's Coinbase wallet being loaded with one of these testnets of bitcoin, and the person said that it's real bitcoin. What surprised me about that is how they were able to make price reflections on that testnet BTC, like the same bitcoin value is showing and displaying in that testnet BTC.

There is a shitty/scammy ethereum ICO thing right now giving people shares in exchange for testnet btc, this is totally screwing up the usability of testnet and also causing antisocial dickwads to waste all our time begging for testnet coins without disclosing that the only thing they want them for is to make a quick buck.

I will be editing posts in this thread to remove any testnet addresses people paste.

Please don't give TNBTC to people who are just hoovering it up to paid by defi scams based on it.

Real testing just needs tiny amount, the people who "need" large amounts are selling it.  (technically trading it for defi testnet defi tokens which they expect to get converted into real value once that scams they are participating in go live).

This abusive and anti-social behaviour has made it hard for people to get testnet for actual bitcoin testing because they've drained all the faucets and conned the people that have historically given it out out of theirs.

It's also forcing bitcoin development to abandon testnet for testing.

Unfortunately, there's a platform that provides unethical services for those who'd like to get something for their testnet coins ^{[as much as I hate to say this, I think we need another reset]}.
