Was investing some EOS for my dad, had to wait a couple of days before I could buy them (cause of money transfer time), and before I had the chance, "poof" from 4 to 8 bucks. Now it's over 12 (got to buy at 8). Might be that there is a correction in January, but even so, waiting is still an uncertainty, I'd say get them while you can. EOS has the potential to become worth 1000's of dollars years from now.
