Before you are thinking about selling, think twice. Bitcoin can pump insanely high since the marketcap is really small and it can potentially go to 100.000+ per coin long term, so 600 to 1000 is absolutely nothing.
The next months will be fun.
still your suggestion is much appreciable because it is the time to hold btc not to sell .
to keep buying and holding it or if wiser that much try playing it inside alt trading while waiting for it to grow more.
