Total Market Cap Predictions for 2018

[King Koopa]

Obviously nobody has the right answers here but I thought it would be fun to get the community's prediction on the entire market cap by end of 2018? Do you see it going to $1 trillion, much more, much less? I personally find it hard to fathom it going 2-5x like it did last year, especially at it's current market cap. I hope I'm wrong and we'll be laughing at this thread a year or two from now
