selling coins in profit and then trying to rebuy lower sounds good in theory, you might actually nail it once or twice
but the issue you have is that certain coins run harder than others on certain days
if btc dumps, there will still be coins performing well
now, you might end up in a position where your coin dumps on a day where the rest of the market performs well
then you are in a situation where you dont want to buy because you assume btc dumping will bring your coin down further
however, your coin is still strong, the day btc dumps, your coin is actually up
now, what do you do? stare at the charts. get stressed. ape back in
but then the next day your coin dumps. so you quickly sell. but price action reverts. staring at charts again. stressed out even more
what's supposed to be a fun enjoyable experience quickly turns into desperate attempts to catch up on gains your hindsight trading brain doesnt stop mapping out
dont worry though, its not just you, we've all been there
how to combat all this? spot n chill baby
