If you go short term (done it myself) here are some tips/warnings.
NEVER USE A STOP LOSS
You see the dumps-out-of-nowhere, yep every once in a while you will get caught by it.
This is called a stop-out if I am not mistaken.
WATCH OUT WITH LEVERAGE AND GOING SHORT
You think you can go lower but you suddenly end up with a market order execution and no money.
Can also be caused by a dump-out-of-nowhere.
CHECK YOUR RATES
Putting in a buy or sell order costs money and you get a crappy rate.
Short term you will have a hard time to get it back.
Never use market orders even if you want to get on the train

If the orderbook is thin you might end up paying 5% more.
MULTI-CULTURE, VOLATILITY, RULES
Bitcoin is traded in many countries 24x7. This means that traditional trading doesn't apply. You can get hit hard at night. Stock never closes.
Analysis is hard if it is volatile, you have no good indicators. Any whale can kill you in a heartbeat.
There is no one that will prevent a whale from pumping and dumping. It is not regulated whatsoever.
AND BUY LOW SELL HIGH

I ended up thinking ... Why risk my shit short term .... HODL makes me sleep better at night.
