meh... it is never good to go "all in". not in bitcoin and not in anything else (stocks, gold,...)
but at the same time, now is the best time to buy bitcoin because price has been low and declining a little bit, so when you find the bottom that is the time to jump in both feet with as much as you feel good for an investment.
before the drop about 1.7Million$ in longs covered. ~6hours later... CRASH! shorts went from ~18K to ~21.7K BTC during those 30min, now shorts continue to rise. and then ~1million in new longs were taken after the drop.
not sure wtf shorters are expecting to accomplish...
... and 3d & 1d RSI is low... like it was between 18th and 22th May this year... before pump to 750+ USD.
