I have a bitcoin miner running 24/7, and I'm earning steady bitcoin
In order to get proper answers, please answer these questions:
[1] is your miner some hashrate bought at some cloud mining website?
If the answer is yes then:
a. There's a huge chance that you have been scammed and you will never see any of the coins they show you on the interface (maybe you should tell us what website it is to check and try to find out)
b. You need to install a wallet software (please ask about it separately) and, if a certain threshold is reached you'll withdraw to your wallet first; then you can spend.
[2] is your miner a hardware you own?
[3] is this hardware miner an ASIC or is it your computer?
[4] do you solo mine or you mine in a pool? if it's a pool, can you please state which pool it is?
[5] usually withdrawing from pools requires a thrashold to be met. Can you please tell the magnitude of your earnings? 0.1
BTC, 0.001
BTC? more? less? (please make sure it's BTC and not mBTC and such).
If you have BTC in the pool, you will need to install a wallet software and put your address somewhere in the pool settings for withdrawal. But again, in order to get there you'll need to know this or that about wallets too.
