The availability of options. Many options for trading cryptocurrencies on the exchanges serve as a benefit for the users. In particular, CEX.IO offers trading opportunities for Bitcoin, Bitcoin Cash, Bitcoin Gold, Ethereum, Zcash, Dash. They can be traded for USD, EUR, GBP, or RUB. Additionally, the variety of payment options, including cards like Visa and Mastercard, as well as wire transfers, contributes to the convenience of the service.
Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction. The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest. Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time.
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]
Bitcoins are mined with powerful computer hardware and software. A maximum of 21 million Bitcoin will be available, after which no further bitcoins will be produced. The algorithm which governs the production of Bitcoin limits the quantity that will be produced, and the rate at which they will be produced. It is a finite commodity – there is a fixed amount, and that ensures that greater demand will always prop up the price. In this way, it is similar to other finite commodities such as crude oil, silver, or gold.

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]
But, once again, be warned. Just because it's a digital currency doesn't mean you won't lose real cash money trading in it. And given that the current Bitcoin market is more volatile than a bag of plutonium nitrate, multi-explosive, sound seeking projectiles, you stand a very good chance to lose a lot of money, especially if this is your first foray into day trading. So unless you have cash to burn or you're already a grizzled day trading veteran, you might want to take one more look at mining after all.
The Bank for International Settlements summarized several criticisms of bitcoin in Chapter V of their 2018 annual report. The criticisms include the lack of stability in bitcoin's price, the high energy consumption, high and variable transactions costs, the poor security and fraud at cryptocurrency exchanges, vulnerability to debasement (from forking), and the influence of miners.[188][189][190]

Speaking of the personal information, you need to know about a certain KYC and AML requirement before signing up. According to some recent regulatory frameworks, the governments have asked Bitcoin exchanges to follow certain identification procedures (just like those practiced by banks) where a user is required to submit their confidential information. These measures are taken to ensure that users do not use Bitcoin for anti-social activities such as money laundering, funding terrorism, drug trafficking, etc.

Besides betting on bitcoin’s demise or rally, you can also try to predict the next winner of the Oscars or bet on which party win control the US Senate after the 2014 elections.

It's fascinating that @jimmysong talks anti-fragility but only sees BCH as an attack rather than an anti-fragility response to SegWit. Maybe someday he'll realize having BCH makes bitcoin stronger -- the hydra dies only after cutting off *all* heads: …
Another issue is the way individuals trade currencies. In addition to the one-to-one trading potential, currency traders can boost their leverage through derivatives and other paper contracts designed to boost returns. In the current environment, some brokers are slowly underwriting contracts that will boost leverage in the bitcoin sector, but such contracts are still in their infancy. Bitcoin trading is more similar to the ownership of an equity on the New York Stock Exchange. Like shares of Exxon Mobil Corporation (XOM), bitcoin is subject to price swings and market volatility.

Bitcoin prices were negatively affected by several hacks or thefts from cryptocurrency exchanges, including thefts from Coincheck in January 2018, Coinrail and Bithumb in June, and Bancor in July. For the first six months of 2018, $761 million worth of cryptocurrencies was reported stolen from exchanges.[61] Bitcoin's price was affected even though other cryptocurrencies were stolen at Coinrail and Bancor, as investors worried about the security of cryptocurrency exchanges.[62][63][64]
