I'm not expecting to get rich, but I'll take $10,000/BTC 31DEC18. LOL! I like the tech and believe in BTC, and have held since 2015. I'm retired and purchased 100BTC then, so I can live off of 10%ROI. 100%ROI/year would be $weet, though...
Just like this moment, people kinda afraid whenever they still want to hold bitcoin or cut loss !
But IMO based on bitcoin graph over 7 years, bitcoin always show a good movement from time to time so I'm just keep hold it as long as possible
