I want advice from all veterans here as what best strategy can be for BTC selling. I want to sell at every pump and buy on every dump. How can one make sure he does not lose it.
What if 4 years cycle is not here this time.
What approach one should get here.
You are confusing me on the first and second paragraphs, what do you really want? Is it a 4-cycle pattern system or how you can effectively invest and divest many times within each 4-cycle? Also, you misused pump and dump in your post, you might want to correct that.
Now, the best approach to divest in Bitcoin regardless of whether it's long or short-term is for you to check out for the FUD in the market, the sluggish moment of not breaking higher level, the closeness of the time to the popular bearish season, and finally, if your technical chart confirms it on the higher time frame.
However, Buy at the beginning of a new bull run, Buy when your technical chart confirms it on the higher charts and Buy when there are impactful events like the ETF saga and the US election periods.
