Here in Nigeria, I have seen at least three people who have built and own a car of their own with their investment in Bitcoin so far and this is not as a result of any jazz but their early investment in bitcoin when the price was still low compare to the price now and the profit margin high
Yeah, you can become a true king with your own castle just if you invest in Bitcoin at the right time. The secret of success is simple 
Sometimes I experience envy because I'm not a lucky Bitcoiner. I wish I had invested in bitcoin all my pocket money when I was 15 so I can don't worry about my whole life. But the past is gone and we should think about the future. I hope someday I'll catch a nice profit from HODLing so I will be able to move to Nigeria or somewhere with a warm climate.
