I need to test the cloud mining functionality to make sure it's working properly. We don't want to risk real BTC.
A cloud mining functionality?
Never seen any that works on chain and therefore would need tBTC for testing. Most of them are just custodial and almost all of them are scam, but let's wait and see if you are a man of your word.
I need preferably 1 tBTC which I will return when I'm finished testing it after about 4 weeks.
You have already received over 1 tBTC. Time will tell if you are an honest or dishonest person.
