Probably like many others, in the first part of 2012 I invested about $10k in some bitcoins that I still continue to keep untouched today. Tell me once again what should I stay away from??
Please cash in at least some of that; it's too sad to think of a conventional amateur investor approach of "always hold out for more" wiping out that potential fortune. Take your 5000x gain and be happy with that phenomenal performance instead of being concerned about the infinite "I could've gotten more if I just sold on Magic Date X".
A materialized gain that you can actually use is more valuable than a paper gain that may not be there when you need it, especially in an instrument as volatile and immature as Bitcoin.
I appreciate your concern. I am keeping them not for more gains, but to pass it on to my child eventually, although I believe single bitcoin will end up costing north of $25,000 since #1 there is only limited number being eventually in "circulation", #2 you can safely use 0.0001 bitcoin to process transaction worth $5.
