Selling a large sum at 5k, a little over 6k in CAD for me. The rest is saved for the years to come

I'm holding since last year and I already sold some of my btc. But actually my goal is atleast 10k$ would be fine thats why I'm still holding my remaining btc.
to me i think this is one of the most difficult decision to take, i think most of the people do not get good profit from bitcoin because the are not good decision taker. for most of the time even they have a good opportunity to buy bitcoin or sell it and book the profit but they missed the opportunity because of low decision taking power.
