for instance $1 million is nothing for bitcoin, we will reach it eventually but McAfee saying it was because he wanted to gain attention not because he made some analysis can made an educated guess!
I don't think these predictions will be accurate.
Although they are celebrities but I see the price will don't go by what they say, because the price is determined by market not them
I read same comments two years ago when someone said 10k dollars until the end of 2017. Price went higher double more! It's not pure guessing it's history. We have 3 more months until the end of this year and we will see last two predictions from litecoin owner and pantera capital, 100k by the end of 2018 form Van-Petersen is failure probably, it's too big rise for so short period of time.
I think 20k by the end is possible, I give less then 20% chances for that to happen, in gambling 20% chances to win are high sometimes.
All in all this is a nice list of predictions made by sound names from crypto world, some are very optimistic, but why not, everyone has a right to believe in what ever they wish. My wish is to see bitcoin over 10k before the end of this year and that to be new bottom, that is reasonable I believe.
