I sold in 2016 autumn, just enough to buy PC parts but clearly that cost me alot to do so. I did later recognize in Feb 2017 BTC was silently stronger then it appeared but almost always DCA is entirely justified. Its normal to be distracted or even worse, fearful, scared to buy and maybe scared into selling.
I don't believe it is normal to get distracted during your time of investment because if you had set out plan for emergency funds and reserves, you wouldn't have considered selling your BTC to buy an ordinary PC even though you needed the PC so badly to enhance some other stuffs you do online but it's bad to sell an asset like BTC just to buy an ordinary PC. This is the area where emergency funds plays an important role because buying the PC was very urgent to you which your emergency funds would have sorted out had it been you made provision for it during your time of investment. It is good for us to know that if you don't want to be distracted by any needs while investing then you must keep reserved and emergency funds because situations like this are meant to occur in the future so they can be taken care of without affecting your DCA and you still keep accumulating.
My understanding of the market is via trading and why it gets the sharp moves like the 2020 low and later rises. When we do pass 70k and confirm it as a low not a peak area, the character of the market will change alot from now.
I haven't accumulated enough so if anything I'm biased to wanting the lower prices tbh; I saw us breaking down to 50k recently and sadly it didnt play out

A failed move to the downside explains why we've risen harder now. Its interesting to me, anyhow I get how all these are games played and not actually the main picture for BTC.
I would have alot more BTC and be better off overall if I had been more bullish on BTC in every state of its cycle, up or down. Trading is generally not the best idea, it'll take up alot of time and most people wont excel enough to ever justify saying they trade a bull market like this; I'd include myself in that but it remains an interest of mine.
This is where you have said the truth because you literally depended on trading your Bitcoins that was the reason you sold your Bitcoins for some short term gains but even after you sold, was it able to solve all your immediate needs? i guess no, that's why anyone who is into Bitcoin investments should remove the mindset of trading at any short period of time despite if the price skyrockets very high. You should consider owning a huge portfolio in the long run than stoop so low on short term gains.
