it doesn't matter what people predict, just keep stacking until you reach the million dollar mark!
I'm hoping 10 btc does the trick but only time will tell...
With 10 btc if you hold long enough I promise you you'll me a millionaire. You may have to hold intop the grave but at least at some point in time them ten btc will be worth a million.
My prediction is 100K+ by 2021
Such promise has no guarantee and I hope time will come that promise will not be broken. I mean, it's fine to be aggressive since we are not blind and we can see how bitcoin is very progressive this year, but putting that big amount without any reservation of failure is not a good investment traits, the basic principle is still should be followed, invest only what you can afford to lose.
