I said it briefly at $532/BTC today. It just dropped down to $520. if you had a large investment (~50 Bitcoins), so that makes a big difference in a few thousand dollars...
Should i keep it for a little longer and hope it jumps again?
Or sell now as it seems to have already peaked?
Selling anytime before the halving block reward and before reaching 1k $ will be considered as a bad move If you ask me . It's better to wait little bit more to make a better profit . After all , Bitcoin is a long term investment .
