bitcoin there are already nearly 10 years and its impact in the field of economics was not significant, I do not agree if it says bitcoin is new era of currency.
When we say the new era of currency that means we will be surpassing the popularity of the currency that are regulated by the government, and IMO this will not happen since the power of the government is very strong as they make and regulate laws. Bitcoin is still the best currency but only considered as crypto currency only, which is a tool to transact online with ease but not possible without people who spend their fiat to convert with bitcoin.
Bitcoin should be considered the new of currency with a few simple facts. No other currency has achieved so much and increased its value by a huge market except for bitcoin.
In over a mere 8 years, the value of bitcoin has increased from a few cents in 2008 to twenty-six hundred dollars in 2017. Crypto-currency especially bitcoin has also taken the online market including the global market like a wildfire. It has already surpassed many other currencies and is still rapidly increasing its value.
