As described in their whitepaper, Augur has set out to create the first decentralized, open-source platform for prediction markets. Based on the ideas of game theory and wisdom of the crowd, prediction markets achieve greater forecasting accuracy than any individual experts can. However, the problem with previously existing prediction markets is that they were all centralized.

Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining.[70]

The technology uses a directed acyclic graph instead of the traditional blockchain. What’s interesting is that unlike other cryptocurrencies, such as Bitcoin, which can have high transaction fees, IOTA’s transactions are free - regardless of transaction size. Confirmation times are quick, and the system is designed to handle a large number of transactions with great speed.
There is also an Ethereum-based ETF pending regulatory review, and many such products are likely to follow. For now, there are just a few options available. For example, ticker symbol GBTC is one such security listed on the US-based OTC Markets Exchange, and is available at major online brokerages such as Fidelity, providing stock market investors a way to gain exposure to Bitcoin without buying the underlying or using a derivative.
NEO began life in 2014. Originally called AntShares, the coin was later rebranded by creator Da Hongfei. To date, it is the largest cryptocurrency which has emerged from China and is sometimes referred to a “Chinese Ethereum” because of its similar use of smart contracts. In 2017, NEO experienced its most successful year to date. From a value of $0.16 per token in January of 2017, NEO climbed to about $162 per token by one year later. This constitutes a return of more than 111,000%. One key to NEO’s success has been its support of programming in many existing languages, including Go, Java, C++, and others. Further, NEO has experienced benefits as a result of its positive relationship with the Chinese government, which is generally known for its harsh positions on cryptocurrencies. As of February 9, 2019, NEO had a market cap of $492.48 million and a value per token of $7.58.
Anyone who has ever sent money internationally knows that today it currently takes anywhere from 3-5 business days for a transaction to clear. It is faster to withdraw money, get on a plane, and fly it to your destination than it is to send it electronically! Not to mention you will be paying exorbitant transaction fees — usually somewhere around 6% but it can vary depending on the financial institution.
Just figure out, what coin do you want to buy and seek for a stable wallet version. As a rule, each coin has its official wallet client. Note that each wallet has its unique address or a tag with a private key that is required to restore your wallet if lost. CoinSwitch never asks your private keys. Store them in a safe place and never show anyone. Once private keys are stolen, your cryptocurrency wallet with all the coins will be lost forever.
“While it’s still fairly new and unstable relative to the gold standard, cryptocurrency is definitely gaining traction and will most certainly have more normalized uses in the next few years. Right now, in particular, it’s increasing in popularity with the post-election market uncertainty. The key will be in making it easy for large-scale adoption (as with anything involving crypto) including developing safeguards and protections for buyers/investors. I expect that within two years, we’ll be in a place where people can shove their money under the virtual mattress through cryptocurrency, and they’ll know that wherever they go, that money will be there.” – Sarah Granger, Author, and Speaker. 
“The factory that I was working in got closed, so I could not find a job for a long time. It made my financial situation very bad for the time being.

I had about 6 educational sessions and after 2-3 months Increased my income up to 85 Euros a day, got my financial independence and even applied to study this field on a professional level.”
1) Irreversible: After confirmation, a transaction can‘t be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.

In 1998, Wei Dai published a description of "b-money", characterized as an anonymous, distributed electronic cash system.[12] Shortly thereafter, Nick Szabo described bit gold.[13] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.[citation needed]
