It's pure speculation if not wishful thinking by someone who likely has a lot of BTC they'd like to see continue to rise.

No one can, with any certainty, predict the future like this article claims to be able to do.

Nobody knows the future. Especially not people speculating on a cryptocurrency that's breaking new ground.

Fair comment: I own bitcoins and plan to keep them for quite a while yet.

Please tell me you are being sarcastic. You are asking how legit a speculation about the astronomical rising price of bitcoin on a bitcoin .com website, with a graph that accurately pinpoints our location in time at the foot of a giant mountain of $$$$$, predicts the downfall of normal money, has no scientific sources.

Consider all "you should buy bitcoin now" to be bait from gamblers who want to maximize their speculative outcome. Bitcoin is nothing but speculation. And right now it is in a ridiculous bubble.

I would flag this if I could.

I don't expect real currencies to plummet but if bitcoins go above $1000 mark, that's pretty amazing.

Do you think the price of bitcoins will rise over the next x years? What value of money y could you lose and be able to shrug it off?

Buy $y of bitcoins, and write yourself a guarantee that you'll sell it in today + x years.

Value for me a while ago of y was $1,500 and x was five years, and I buy $150 a month every month on the same day, with a get-out clause at a specific valuation.
