Hi all,
does it make sense in xrp, take profits and then naturally go back to a higher price, or is it okay to do no sales at this time?
Sorry for the bad English ...
Honestly, I don't think anybody ever knows. It is definitely the case that massive rises tend to be followed by a sudden steep drop, typically losing around 1/4 or so of the amount of increase. The problem is, you really don't know when the rise is over until you see a drop afterwards. You also see small drops followed by large increases.
If you define an increase as ending whenever there's a big decrease, then every increase will be followed by a big decrease. The problem is that you can't tell when the increase is over until you see the decrease.
I don't think anybody can successfully time the market consistently or with odds that much better than chance. You can certainly sell only when the price is higher than your buy and buy only when the price is lower than your sell. But you'll find yourself on the wrong end of just as many price movements as you are on the right end of, just like everyone else.
