This is a very high value and I don't think bitcoin will hit this price in two years time.
Compare to John McAfee's prediction by that year, $1,000,000 for real? That's the highest value of bitcoin that we've heard for this year.
Before he said it was only around $500,000 but after the all time high on December, he said that everything he expected was doubled so he moved his prediction to a higher value.
$91,000 on 2020 is realistic than the rest. Halving will occur on that year so it's expected that price will increase.
I am not sure to this prediction that will be increase $1,000,000 this is too much
100k USD is possible by 2020.
