And buying 100 btc for 1200 really would have been better.
It is difficult (and maybe not realistic to hypothesize like that) to just pick a lump sum price, and to say that I could have afforded to buy 100 BTC for $12 each and then mostly have had been able to hang onto them for 12 years blah blah blah... when the fact of the matter was that you were shedding BTC for almost all of those last 12 years... except maybe more recently you are trying to figure out how to hang onto more BTC, but you still seem to have an ongoing dollar biasness that makes it difficult for you to hang onto your BTC...
That's part of the reason that dollar cost average buying is better for really solidifying a position is that it can end up taking place over a decently long time and will also have better chances of facilitating strong hands and longer term thinking in regards to maintaining the stash ... and don't be trying to sell BTC in order to buy more BTC at cheaper prices. even though surely if you are in a business (the mining business) that causes you to have regular income coming in through BTC, then you are somewhat of a forced seller.. but you still need to figure out your HODL mostly cold storage targets along the way.. so let's say even if you had regularly screwed up and you are kind of continuing to regularly screwing up (maybe you cannot be fixed), but just for the sake of other members who might find themselves in similar situations, there are needs to accumulate and to keep some of that value in cold storage so that you are not tempted to sell it and to try to buy back later..
Sure selling small amounts of BTC on the way up might be o.k... but ONLY small enough amounts that you are not really depleting your principle.. although with more elderly people who are getting into their 60s or even late 60s, they might not really be in any kind of accumulation stage anymore but instead either maintenance or even perhaps quite likely liquidation stages.. so once you get to a more elderly stage, you likely are considering ways to spend your wealth.. but if you are not sure how many years that you might be living then you may well be teetering more between liquidation and maintenance and maybe not even trying to spend too much too quickly.
None of us can know the exact solution for anyone else.. even though we may well realize that if we have an investment timeline that is 4-10 years or longer, then we may well be mostly trying to focus on BTC accumulation through the three most common BTC accumulation methods of DCA, buying on dips and lump sum investing.. while at the same time keeping a kind of eye on the prize of making sure that our BTC is mostly growing while we are in the accumulation stages, and if we spend any BTC, then we are doing spend and replace
Hopefully replacing with more BTC than the quantity of BTC that we had spent, even if it might cost us a bit more if we don't time some of our spend and replaces very well... and shit does some times happen.. including mistakes sometimes happen along the way too.. maybe the mistakes are in a state of almost inevitable. For sure, I am not even suggesting that I am free from mistakes. I am still making little tweaks here and there to continue to figure out ways to take advantage of my mid-June Binance US windfall in which I ended up with quite a few extra Tether USD.. since within hours (or was it minutes) of the actual windfall, I had pretty much bought back more than 125% of the quantity of the BTC that I had sold, just so that I could at least lock into place that I would not end up with fewer BTC out of the whole situation.. so even if I already feel that I have more BTC than I need, I did not want my mid-June windfall to cause me to have fewer BTC than I had planned to have had - even though I had received a premium price for many of them, and even if I used all of my remaining USDT to buy back more BTC at these here prices, I would be able to buy a decent quantity of BTC --- and part of my point in referring to mistakes is that no matter what any of us might do (or decide to do or to plan) then there are going to be dilemmas and potentially a variety of paths forward and some paths are more obvious than others, and some paths have a variety of tradeoffs that need to account for personal factors. and the various better solutions (since there are probably more than one) are not always clear.
