This is becoming typical that whenever we get a raise, the market will start to dip a bit and will come back suddenly for another quick pump.
if you are not a long term investor then you must learn how to take profit , price won't keep going in one direction forever, 5400$ was an excellent price to sell for , that was a 60% increase from the last low , day traders and short term investors will take profit and price will drop, that's normal, it will always happen.
as for the 5000$ it does not make sort of support, the only proper support below 4950$ which is very weak will be at 4.6k and the stronger one is at 4.2k-4.3k.
good luck.
Well, there's always a next time for it.
