Monero is an open-source cryptocurrency which focuses on privacy and decentralization. It means “coin” in Esperanto. It masks the sender, receiver, and the amount of transaction. New updates in 2017 like confidential transactions and ring signatures improved its privacy even more. Most javascript miners mine Monero. These are mining scripts which use a website visitor’s computer for mining instead of displaying advertisements to the user. Because it is ASIC resistant, botnets may be used to mine this currency. Various dark-net markets (where illegal goods are traded) use Monero because of its fungibilityand privacy. Monero is also used by other coin-users as a coin-mixing service to try to hide the ownership of coins which don’t have the same privacy features.
