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]

When issuing a transaction in IOTA, you validate 2 previous transactions. This means you no longer outsource validation to miners which requires wasteful amounts of computing power and usually a large stake of coins. These required resources are, in effect, centralizing the currencies which many believe were created to be decentralized in the first place.  
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet.[71] The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable).

Nxt: Not only does this nifty coin sport a name similar to Steve Job’s other company; it uses a cool and different algorithm for producing coins. This algorithm – an implementation of a proof-of-stake scheme rather than proof-of-work – may be less burdensome on the environment and has long-term potential. It may be worth a tad less than the other coins we recommend; it is worth about a penny on the dollar on a good day. However, less cost per coin means you have less to lose if the coin value deflates. Nxt is like Namecoin. It had a super cool code but didn’t though perform at the same level as other cryptos (until late 2017 where it saw a notable price hike). It is still priced very low in USD.

The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme.[14][15] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.[16]
