Everybody's life will change when bitcoin will reach $100k not only by the end of this year but in that time it will. We can already have a good life when bitcoin has reached $20k - $60k then what's more if bitcoin reaches $100k and more? We're for sure going to have that much profit in that time and it's all about the timing that whenever it approaches near to its price then you have to make sure that you're still holding by that time. And while waiting for the price to be reached at that time, keep stacking more bitcoins while it hasn't reached it yet.
