It feels really bad going through my portfolio on blockfolio to see massive downward movement in the value of my holdings. I really don't know if this is the usual market correction we have periodically or the end of the bull run. Is it wise to keep holding or take what's left?
Market corrections doesn't have specific range to call it as "usual". Corrections are inevitable and that's a nature of a highly volatile market. Whether it's a short correction or sharp correction that's still called a correction, a sudden declination of price after the bullrun.
Now the question is, is it wiser to take what's left even If it means you're not profiting just to avoid further loss?
Of course not. As long as you're not holding the shitiest coin, I guess you're fine to hold it and wait till it pumps back again.
Market cycle goes up and down. Not all the time the price is on top.
