Ethereum: an open-source cryptocurrency launched in 2015 and proposed by Vitalik Buterin, Garvin Wood, and Joseph Lubin. It is based on the blockchain model whose main objective is the decentralization of the market. In 2016 there was a fork from which the Classic Ethereum emerged. Currently and since its inception, Ethereum ranks second in tems of the market capitalization.
By providing a decentralized solution, Augur allows people from anywhere in the world to ask a question about the outcome of a future event, as well as buy and sell shares on the outcome of any market they wish to participate in. Moreover, it allows thousands of users to report on outcomes, thus removing the need to trust in an individual reporter.
One of the key differences between 0x and other decentralized exchanges is that 0x is fast. To reduce blockchain bloat, all orders are transported off-blockchain and later verified. In addition to making transactions quick, this removes the necessity of spending gas to pay for network transaction costs, like on other decentralized exchanges such as EtherDelta.
Ripple: Similarly to Bitcoin and Ethereum, Ripple is a decentralized payment system based on open-source. In fact, the project came years before its competitors, specifically in 2004 at the hands of Ryan Fugger. However, it was not until 2016 when he obtained the license to operate it. Unlike the previous ones, Ripple does not have mining operations nor will new currencies be created in the future. It is the third largest cryptocurrency in terms of market capitalization.
There are fees involved with buying from Coinbase and some types of trading on Coinbase Pro (which can in cases get lower as you buy / trade more). Other exchanges have better rates than Coinbase (for example Coinbase Pro itself has better rates). However, rarely do exchanges have a better fee schedule than Coinbase Pro. In other words, when using Coinbase specifically, you’ll pay a little bit more than market price (or sell for a bit less than market price) and pay a small fee when trading on Coinbase (this is a trade-off for ease of use). NOTES: To be clear, there are essentially two sets of fees when you buy with Coinbase. One is them charging you more per coin than on Coinbase Pro or other exchanges; the other is an actual fee (currently paid in crypto, not USD, so if you buy 1 Ether, you get a little less than 1 Ether but pay the market price). That is the price you pay for them doing all the work and taking the risk of the price changing quickly when you buy. Not a reason not to use Coinbase and only use Coinbase Pro every time, but it is something to keep in the back of your mind if you start making lots of buys.
“If the trend continues, the average person will not be able to afford to purchase one whole bitcoin in 2 years. As global economies inflate and markets exhibit signs of recession, the world will turn to Bitcoin as a hedge against fiat turmoil and an escape against capital controls. Bitcoin is the way out, and cryptocurrency as a whole is never going away, it’s going to grow in use and acceptance as it matures.”
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.
