But how do miners make profits? The more computing power they manage to accumulate, the more chances they have of solving the cryptographic puzzles. Once a miner manages to solve the puzzle, they receive a reward as well as a transaction fee.
Open-source and global, Litecoin, like Bitcoin, is also fully decentralized, with mathematics securing the network. Some people point to Litecoin’s faster transaction times as an improvement over Bitcoin.
“This automated system will follow the money and tag any account that receives tainted funds. NEM has already shown exchanges how to check if an account has been tagged. So the good news is that the money that was hacked via exchanges can’t leave.”
Money is at the heart of the financial system – its most basic element. Fundamental reform of the system starts with addressing how money works today and how it could work in the future. The emergence of digital currency has led several central banks to consider how this new technology affects their ability to discharge their mandates. One of the most significant questions is whether digital versions of fiat currencies can be issued and what the role of the central bank should be in a financial system being changed by new technology.
2018 seems to be a good year for cryptocurrencies and blockchain technologies. 2017 was full of controversial anti-crypto statements by governments and banks appearing to push with all their might against crypto use. This triggered …

In the U.S., the IRS has ruled that Bitcoin is to be treated as property for tax purposes, making Bitcoin subject to capital gains tax.

The issued guidelines contain an important caveat for Bitcoin miners: it warns that anyone creating bitcoins and exchanging them for fiat currency are not necessarily beyond the reach of the law. It states:
In 1983 the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash. Later, in 1995, he implemented it through Digicash, an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or a third party.
Careful regulation, then, could protect blockchain projects from a hugely damaging bust. And the model is genuinely utopian enough to deserve nurturing. Cryptographic tokens effectively make all of a platform’s users part-owners. Anyone selling goods for Bitcoin, for example, has had a chance to benefit from its huge price boost over the past year, while Facebook and Google users have not shared in those companies’ growth.
