Most cryptocurrency exchanges will serve their intended purpose in letting users buy cryptocurrency listed on the exchange. The main differences are the exchanges fees, customer support, the number of supported coins, and supported countries. To ensure you have access to as many cryptocurrencies as possible, it may be wise to sign up for each exchange.
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.

The cryptocurrencies are a solution to many of the obstacles that the traditional financial system currently has, sending money to different parts of the world is expensive, sometimes delayed and in some places it is not possible to do so. We are in a globalized era and cryptocurrencies help make financial transactions fast, secure and low cost. There are projects with a great vision, for example, the cryptocurrency Ultrapoint has the mission to become the first currency for global and practical use in all sectors of the economy. Then when a cryptocurrency achieves massive use, then its benefits will be fully understood.
One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand.
Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto.[23]
