I'ved tried my luck on ethereum mining with this https://github.com/angelomilan/ethereum-guides/blob/master/GPU-cloud_mining.md And I think I have some ethereum.

> eth.getBalance(eth.coinbase).toNumber();
5000000000000000000
> web3.fromWei(eth.getBalance(eth.coinbase), "ether")
5

UPDATE: I tried to send using this but has this error:

eth.sendTransaction({from:eth.accounts[0], to:"0x21389ab987979ae987", value: web3.toWei(0.0005, "ether"), gas:5000})

Error: intrinsic gas too low


> eth.getBlock("latest").gasLimit
5003

> net.peerCount
0

What is intrinsic gas too low and how to solve this, my gasLimit is 5003. What is all this and how to I would say pump more gas ?

My question is now how do I convert it to cash ? I cant figure that out. I believe on the .ethereum hidden folder contains the coinbase wallet. How do I then cash it out ?

  • Hi there. Ignoring the error for the moment, but are you sure you were mining on the main network and not a test network? (By February, when you posted the question, we'd already undergone the Byzantium fork, which reduced the block reward to 3 ETH. Your coinbase account has 5 ETH in it.) – Richard Horrocks Apr 9 '18 at 14:06
  • how can I find that out ? You know I have 20 ETH now, thats really strange so if its true I want to cash it out. If its real, Im willing to share it off with you. – Axil Apr 9 '18 at 14:09
  • 20 is a multiple of 5, so if you've mined any of that recently, it's not going to be on the main network. What hash rate were you getting on the AWS machine? (etherscan.io/ether-mining-calculator) – Richard Horrocks Apr 9 '18 at 14:16
  • geth. i followed the instructions here:github.com/angelomilan/ethereum-guides/blob/master/… – Axil Apr 9 '18 at 14:19

    If you want to continue with this route, I'd suggest restarting Geth and waiting until the full sync of the blockchain has completed. (It can take quite a while.) – Richard Horrocks Apr 9 '18 at 14:43

Minimum required gas to send transaction is 21000 units. So simply use 21000 or more instead of 5000.

  • How to use 21k or more? – Axil Apr 13 '18 at 13:03
  • Just change gas parameter like : eth.sendTransaction({from:eth.accounts[0], to:"0x21389ab987979ae987", value: web3.toWei(0.0005, "ether"), gas:21000}) – Kerem atam Apr 13 '18 at 13:04

There are quite a few ways you can cash out, but they will mainly depend on where you live. If you're in the states I believe you can do a deposit to your bank account through their website. Personally though I've had troubles depositing money from exchanges into my bank accounts, and have had my accounts temporarily closed due to the fraud concerns banks have with cryptocurrency. I tend to opt for sites like localbitcoins, localethereum, or even some ATMs which have low fees although that can be hard to find.
