the reason is very easy to explain. why do I choose bitcoin? for me bitcoin is a currency that can be a future for everyone, especially those who play it. trying to live from the ordinary to the more overlaid is a desire for everyone. let alone in an easy way. I think bitcoin is a perfect solution to achieve that goal.
The reason they chose bitcoin is definitely want to change their lives for the better, because bitcoin is the best solution to help finance and economy for those who use it and besides it can realize the desire that has never been achieved. but it all depends on hard work and passion for those who use it to achieve what they expect, bitcoin is a boon for everyone who wants to change his life for the better.
