How much down can you take without ending up in debt when all is said and done?
Maybe bitcoin is greatly undervalued in your eyes, but to the general public, it's crap and nobody is buying. Hence, why price has been falling all god damn year.
Lesson number for trading: Don't fight the tape.
Lesson number 1 for trading: DON'T TRADE!!!1111 (rather invest)
Rule #2: Set a stop loose. Don't let your investment fall any more than 1 or 2% before cutting looses. That would have saved OP.
trading and investing are two different things...
And investing in appreciable assets -- such as a diverse portfolio of stocks and bonds -- and investing in speculative digital tokens are two different things.
Any speculative investment should have a stop loose, which many here decided to forego and instead blindly hope that their hail mary pass would boom again. Bitcoin is going down... if you didn't cut your looses yet... it's still much better to do it late than when it's down to <$100, which will come, trust me.
Nothing should have a stop loss. Selling simply because the price of something you hold (and no other reasons) is just about the most stupid thing you can do in your life. If price goes down you buy more, when price goes up you can contemplate selling.
Oh and for the record the term is stop loss.
