@OP, I saved your ass last time when you wanted to buy in the 820s by saying we would see 700 soon. And I still don't think it is a good time to buy.
The OP seems a near certainty to get slaughtered. He aint even bought any BTC yet and he is getting all fixated with all the Bitcoin to a bazillion USD within the next 12 months theories, backed up with log charts with lines drawn on them of course. He has got his hands on 12K USD, and imagining what life would be like if he could multiply that by 10, 20, 30, etc
Bitcoin will probably trend at $700 range for a few days. The OP will get impatient and will convince himself that Bitcoin has shown strong bottom support at $700 and that the trend has reversed. He will look to users of this forum for the bias confirmation that he wants to hear and he will of course get it in bucket loads. His attention span and personal bias will prevent him from even reading two single sentences from anyone who advises that caution be exercised. The OP will likely start entering the market right at this range. Within a few weeks, he will find himself around 30% underwater. He will look to this forum for moral support, he will again get to told to HODL, and be commanded to put as much new fiat as he can muster into these unbelievably cheap Bitcoins. Then Bitcoin will really tank as the true final capitulation hits. He will be 70% underwater by then, at which point, he will sell everything.
As Bitcoin bounces back, he will jump back in with the little capital that he has left, right at the top of the bounce. Bitcoin will then slump back down. He will sell taking a further 40% haircut. Bitcoin will spend a period of time in doledrums before building up support for another bull-run. A bull-run the OP will not be in a position to take advantage off.
The OP specifically said he isn't looking to flip it for a quick buck. I know you are still having trouble understanding how any could possibly not be a trader, but what if he just buys and holds?
If he doesn't need the cash, and is happy with the risk that it could go to zero. It's a 50/50 bet that he could get more or less by waiting. I've also plunged in headfirst at $15 and then regretted it for months as I took a *87%* haircut on capital. I've also sat on the sidelines at $5 waiting for cheaper coins, missing out on picking up hundreds more, and then regretted that forever.
12k gets about 17BTC right now. If you believe in the moon or bust theory, thats not a bad holding...
