In this world of corporate world, where money is controlled by rich corporate lords,banks and governments and poor people are let off with enough money to meet their both ends, crypto currencies are fresh start for the people. Money,freely available to anyone willing to buy, by which a middle or lower class person can benefit from is the reason for its popularity and use.
It has its own pros and cons but to know that after research and some hard work, you can BENEFIT from it is why i would recommend everyone to look in to this new crypto world and may the power of "all greens" be with you :p
