Although bitcoin was the first coin other coins have been created with their own unique selling points. These “alt coins” include Ethereum, Litecoin, Dash and many others. The top 30 coins are very liquid and traded on many exchanges.
The first alt coins appeared in 2011. Their aim was to overcome Bitcoin's technical limitation . As of the beginning of December 2017, there are over one thousand alt coins.
Coinmarketcap.com portal contains data on 904 altcoins traded on exchanges, although according to some estimations, their number exceeds one thousand. Nevertheless, in the total capitalization of the cryptocurrency market in the amount of more than $343,586 billion, Bitcoin still takes the dominant position.
Disadvantages of Bitcoin
The developers of alt coins primarily solve problems that are present at Bitcoin.
Among such disadvantages there are:
- Long transactions. To speed up the transactions' time, other algorithms are used. In addition, the cryptocurrencies with a smaller block volume calculate the necessary operations faster.
- Lack of anonymity. Although the cryptocurrency transactions are considered to be encrypted enough, still, the sender and receiver may be tracked. To avoid it, some alt coins use addition methods of encrypting.
- Difficult and expensive mining. Constant complicating of Bitcoin mining requires even more resources to form new blocks in block chain. Altcoins offer alternative mining protocols, which allow the users to do it without any complex equipment.
- Insufficient functionality. Bitcoin is a cryptocurrency and its primary task is to be a tool for settlement transactions. Altcoins add extra functionality, for example, the creation of smart contracts.
Many of altcoins are built on the basic structure, provided by the Bitcoin block chain, i.e., they are in fact its forks. So, the majority of altcoins are single ranked, include mining process and offer effective and cheap ways to carry out transactions over the Internet.
