This year is perhaps the best example why hodling is way more profitable than trading. We had 4.5x raise of the price with 2 very short lived dips 20%+. If you are telling me that you predicted both dips and didn't sleep to catch the bottoms, then you are the best trader in the world. But the truth is that 99.99% of the traders didn't sold just at the moments before the price dropped. In all cases hodlers had the biggest profit. However, I must warn you that I sense some complacency and over confidence, that may play a bad game in your future trades. Based on the probability theory and the testimony of many traders, 10 successfull trades may and will be completely annihilated by the 11th, even if your are genious. And then you will be vulnerable to the negative emotions and make other bad choices which may bring a substantial loss. Your philosophy is proven to be wrong by the founders of the HODL movement. Bitcoin is not a shitcoin to be traded for 10% profit and then dumped. If you think so, better go to Poloniex or Binance and trade shitcoins.
I respectfully disagree. I am significantly better off for trading with a part of my stash - what I call the play money. At heart I'm a hodler, but I can't always (ever?) buy as much as I'd like, so a bit of trading on the side helps a lot. As to the 11th losing trade annihilating the previous 10 winning ones, I think it boils down to being careful and sticking to a reasonable quantitative plan. You win, you take it off the table. You lose, you lose and eat it and go on.
Of course, looking for exact tops and bottoms is a recipe for disaster. My point is, you don't need to catch the extremes to be profitable.
Disclosure: I've got a green long position which I'm getting a bit impatient to close, and a smaller short position, in the red, which I'm hoping to make a bit larger averaging up, ladder style. When the two positions are equal, my net position stays put, more or less, since one makes up for the other. Then it's a game of consuming the winning side and then the other one, aiming to reach the null point (0 long, 0 short).
