“In 2 years from now, I believe cryptocurrencies will be gaining legitimacy as a protocol for business transactions, micropayments, and overtaking Western Union as the preferred remittance tool. Regarding business transactions – you’ll see two paths: There will be financial businesses which use it for it’s no fee, nearly-instant ability to move any amount of money around, and there will be those that utilize it for its blockchain technology. Blockchain technology provides the largest benefit with trustless auditing, single source of truth, smart contracts, and color coins.”

Bitcoin Gold (BTG) is the second fork from Bitcoin (i.e. the second version to stem from Bitcoin’s source code). It retains Bitcoin’s transaction history, meaning that if you owned Bitcoin before the fork, you now own the equal amount of Bitcoin Gold. This cryptocurrency aims to introduce an alternative mining algorithm that is less susceptible to ASIC-based optimization, therefore allowing users to earn more with their computer cycles.
Monero is a secure, private and untraceable currency. This open-source cryptocurrency was launched in April 2014 and soon spiked great interest among the cryptography community and enthusiasts. The development of this cryptocurrency is completely donation-based and community-driven. Monero has been launched with a strong focus on decentralization and scalability, and it enables complete privacy by using a special technique called “ring signatures.” With this technique, there appears a group of cryptographic signatures including at least one real participant, but since they all appear valid, the real one cannot be isolated. Because of exceptional security mechanisms like this, monero has developed something of an unsavory reputation; it has been linked to criminal operations around the world. Nonetheless, whether it is used for good or ill, there’s no denying that monero has introduced important technological advances to the cryptocurrency space. As of February 9, 2019, Monero had a market cap of $808.50 million and a per token value of $48.18.
Zcash, a decentralized and open-source cryptocurrency launched in the latter part of 2016, looks promising. “If bitcoin is like http for money, zcash is https," is one analogy zcash uses to define itself. Zcash offers privacy and selective transparency of transactions. Thus, like https, zcash claims to provide extra security or privacy where all transactions are recorded and published on a blockchain, but details such as the sender, recipient, and amount remain private. Zcash offers its users the choice of “shielded” transactions, which allow for content to be encrypted using advanced cryptographic technique or zero-knowledge proof construction called a zk-SNARK developed by its team. As of February 9, 2019, Zcash had a market cap of $291.25 million and a value per token of $49.84.

As of May 2018, over 1,800 cryptocurrency specifications existed.[24] Within a cryptocurrency system, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners: who use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[14]
