First decade of 21st century is started with bubble burst of Computer Technology or Information Technology. That time everybody think that we as a human giving too much importance to computer technology and it will not get us too far and bring trouble. The biggest example of this is Y2K, which made us to think that Information Technology and programming is at death bed. But engineers and programmers pass that phase of uncertainty as enter in the new century along with new hope to make this century as successful as last century for mankind.
Since then computer programming and hardware capacity increased multifold, which help us to improve our life. Especially, hardware is going tiny and tiny everyday. This gives us too much power in our hands to use small gazettes which we can carry in our palm.
Internet has added one more dimension in computer technology and started era of free knowledge, which any one can pass at the speed of light. Bill gates, who is founder of MICROSOFT stated in his book that without internet mankind would not be able to use computer technology as its fullest. With the help of programs and internet we have managed our life so well that it looks like the end of evolution of computer technology.
But in the year of 2008 Satoshi Nakamoto released white paper and introduce world with new type of currency, which he called BITCOIN. Since then so many kind of cryptocurrency or so called digital currency has evolved. Everybody talking about it and imaging it as currency of future. So we don't need to carry paper or polymer notes of currency in our pocket. We just need to carry our phone with digital wallet with us and we can pay for any service or goods with that digital wallet. Sounds like a great IDEA.
