If you are mining Bitcoins, you may want to reconsider. A new study from RWTH Aachen University shows that the ledger used to verify transactions includes illegal content, such as child abuse imagery. The ledger is stored locally on the miner’s computer, and because that content is on your computer, you are liable for it…. We’re still in the beginning of Bitcoin, don’t get too carried away.
