Holding is the safest but isn't worth it to me.

I think everyone should sell after major pump and buy whenever the coin dumped.even if you don't TA, you can at least gain 5-10% by doing this.

After a pump, there's always always a correction. It happens on btc, eth and on all alts.

You will never sell at top nor and buy at the bottom, but you will gain Satoshi in the process.
