So here, what we really want to understand is the probability of bitcoin reaching $500,000. The market cap will have to be $8 trillion dollar for bitcoin to hit that landmark. So do you think there is a little probability for that???

Im believe, nothing imposiple in cryptoword, mc afee is the best promotor in cryptocurrency, He must have a reason to say bitcoin for $ 500k in 3 years,
John mAcfee is the paid shiller I think we should also do our own research instead of following him. Yes there is the high probability in 2020 for crypto market to hit mainstream and this mainstream can lead all major cryptocurrency values to the 5x or 10x. But I don't think the price speculated by John mAcfee is realistic.
