I see a lot of cries for HODL! and I think a lot of people are missing a huge aspect of hodling:
selling and buying
It's been said a thousand times, but basically: sell high buy low.
If you take the time to study market trends, learn about market economics, and keep in touch with developments in the crypto world, you actually can predict when a bull market or a bearish market will happen.
For example now, the market has been extremely stable for the past month and a half and has been gradually increasing for about a week.
We are finally going to see a bull run soon.
Since April and May are typically big months for crypto conferences, then I would say early to mid may is when it will take off, I might be off by a couple weeks.
So all you have to do is crunch the numbers.
Sell when it hits an acceptable profit range, then go right back and buy the exact same coins when the prices go down to your target point.
For example, last december you could have sold btc for around 17 to 19k, then you could have recently bought more for around 7 to 8k.
Now, the btc will surely hit 20k in the next bull run.
Am I over simplifying things? NO!
Well, you have to crunch numbers but it really is a simple trading principal.
Personally i will never go there, I once tried what you are suggesting and my portfolio decreased by 25% because of the trade charges and the risks involved.
My HODL means never touching my bags no matter what, i have goals for my portfolio some 5 years other based on the price target.
I’m currently learning how to day trade as its riskier than holding and once i’m good at it - i will dedicate some amount to trade with - an amount i’m comfortable losing.
