As price is not stable for crypto currency like bitcoin. It can be up or down any time. But yes we can predict and conscious about it to protect our money from loses.
From trading a short term profit I stopped doing that it's time consuming and the market is very unpredictable, just when you thought things are moving nicely you wake to see there's a dip even though you are confident that the buy support shows strength when you left it.
Plus the stress of monitoring the market for your short term goal, and this is also why I stopped day trading. Bitcoin failed to hold on a $12k position and that’s why we saw a little correction but if bitcoin keeps on failing them we will touch again the $9k in time, so stay focus and know when to cut losses and take profit.
