Newb mistakes:

- After hearing about bitcoin, discredit it based on horrendously misguided and biased 'information', derived from mainstream sources.
- Waiting several months or years, during which time the price appreciates 1 or several orders of magnitude.
- Deciding to buy after the next dip, leading to panic buying near the top before the next crash.
- Buying too late and with too great % of portfolio, instead of as early as possible with quite small cash outlay.
- Selling after a runup in anticipation of a crash. (Only sell when you are manic to buy since 'it's going to the moon')
- Selling after a crash in anticipation of buying back cheaper. (Never happens, sorry.)
- Selling after a too small gain with no strategy and no need for the funds ("I sell after 20%, 50%, 100%..." <-dude, bitcoin's appreciation so far is 50 MILLION %, want to reconsider..??")
- Selling, because you believe bitcoin has reached a 'bubble top' or a 'fair value'.
- Selling a too great % of holdings, such as going totally in and out.
- Selling.
