If someone just listened to you and managed to buy at $6,700 now he's on profit.
The current price now as I type this reply it's now at $6,900 so there's a $200 within a single day so that's a very sweet profit. But this isn't the end of those profit because the big recovery is about to come.
Buy now, sell after 6 months.
LOL. Thats as if he's buying 1 btc, also ignoring the current buy/sell price on exchange plus the interest. I think he would not profit that much as you said.
