Within my maintenance system, since 2015, I have been selling as the BTC price goes up and buying as it goes down, so yeah, I buy bitcoin regularly on dips. My way of selling has evolved through the years, and I think that I first was selling close to 10% of my stash for every time that the BTC price doubled in price, and these days I probably sell less than 3% of my stash for every time that the BTC price doubles.
If I may ask sir, where you selling close to 10% of your Bitcoin back then because you didn't believe in Bitcoin ( you didn't see the potential) and is it because you have seen the potential of Bitcoin that is why you are now selling less than 3%? I guess What you were doing back then was spot trading not really an investment and I believe you would have gotten more fraction or number of Bitcoin by now if you have not being selling close to 10% of your Bitcoin. However, I think the most important thing is that you have a good portfolio and whether you sell or not it won't affect you in any way. if you knew Bitcoin will be this great will you still be selling close to 10% then?
