Cryptocurrency adoption has been moving really fast in recent years. The statistics in 2021 have been the most impressive to date. For example, the daily number of Bitcoin transactions averaged around 300,000 in May, and the initial public offering of the US cryptocurrency exchange Coinbase in April saw it debut on the sharemarket with a market capitalization of over $80 billion.

For those who are looking at Bitcoin as an investment opportunity, research shows in the last 10 years it is the world's best performing asset - rising 9,710,233% from the end of 2010 to the beginning of 2021. So there are certain advantages of crypto over fiat money that let us say digital currency use is only going to grow in the next few years.

Bitcoin has already become a popular alternative to fiat currency transactions, and El Salvador recently became the first country in the world to give Bitcoin 'legal tender' status - giving it the same legal status as El Salvador's fiat currency.
