Additionally, users can set security questions, which makes it a lot more difficult for hackers or bad actors to get into their accounts.


This UK-based project was initially launched in 2013. However, it was originally a cloud mining service known as GHash.IO. After a year, the platform's mining pool was comprised of many Bitcoin owners and even contributed to upwards of 51% of the entire Bitcoin mining power. This essentially allowed its clients to use CEX as a solid tool when it comes to cashing out BTC tokens. That said, in 2016, all of the mining processes ended up getting suspended.

Cloud mining is a process of mining for cryptocurrencies in the form of a group, or a pool, where users essentially share processing power in the cloud and, as such, do not need to purchase or own their own hardware. By doing so, they are paid out a share of every block reward which the pool earns.

Since 2014, the service has been implementing exchange functions, which increased the overall number of users.

GHash.IO was founded and owned by CEX.IO, which is a cryptocurrency exchange that continues to operate to this very day. Alongside hosting a multipool for mining altcoins, it hosted separate pools for mining Litecoin, Dogecoin, and others.

The synergy here occurred when traders on CEX.IO could buy shares of GHash.IO mining hardware with the goal of operating a mining pool. GHash.IO closed in 2016, which led the way to CEX.IO to continue operation initially as a Bitcoin exchange.

GHash.IO plays a major role in the history of CEX.IO. However, it did have its flaws. Due to its popularity, many people within the Bitcoin community had worries about the possibility of a 51% attack. Remember, at this point in time, GHash.IO did indeed have this much BTC. This is a type of attack that can happen when a single mining pool is able to mine multiple Bitcoin block rewards in a row, which could be problematic for the entirety of the Bitcoin network due to the fact that it would allow the mining pool to double-spend or counterfeit BTC tokens.

In July of 2014, did indeed briefly exceed the 51% threshold and forced the community to find a solution. Mainly, the pool developing the majority of tokens ended up resulting in Bitcoin developer Peter Todd selling half of his holdings.Temporary measures were implemented, in which released a voluntary statement that they would not exceed 40% of the overall bitcoin hash rate.Additionally, they stated that a new committee would be created to act as a watchdog against the 51% issue, which would include representatives of the mining pools, Bitcoin businesses as well as other specialists. However, in 2015, GHash.IO’s pool fell to 1.99% of the total hashrate and closed in 2016.This meant that while the mining pool was terminated, CEX.IO lived on solely as a cryptocurrency exchange platform.
