Wow damn, trying not to panic sell. Bought 17.5 Coins at 766$ 2-3 days ago. I´m nervous to lose my 13.5k$
Rule number one on bitcoin : do not sell on weekends.
I've been buying since Feb this year. My last batch at $740 may not have been the best price, but they're certainly better off in Bitcoin than my bank. The last two times I sold to buy in lower during this rally resulted in a loss - so time to switch off the computer and forget about them.
I didn't lose any USD - but I did lose BTC. If you don't need the USD right now, leave them alone!
