There are also Peercoin slots available to use on some online casino platforms. Peercoin is a form of cryptocurrency that came about in 2012. It was inspired by the open-source code for Bitcoin. However, Peercoin is different than Bitcoin in that it uses “proof-of-stake.” What this means, is that the Peercoin cryptocurrency will grow with interest by a certain percentage point annually. It may be 1 percent, or that may change at another time. A customer must hold Peercoin and verify their stake in the network, but the rewards can be similar to holding money in a savings account with this cryptocurrency. Peercoin is also energy efficient, as well as stable, and secure for transactions. With that in mind, Peercoin slots may make sense to some customers as a way to store winnings and collect more money on top of their winnings over time. Buying Peercoin (PPCC) is similar to buying the other cryptocurrencies like Ethereum or Litecoin. A customer needs to have an account on a cryptocurrency exchange, link a bank account or debit card, and then use available US dollars or “fiat” currency to make a purchase.
