If you want to hold for the long term, they should focus on holding the bitcoin and increasing their satoshi amounts, regardless of the price of the bitcoin. Those who are able to hold for long term and not tempted to sell, your portfolio will continue to increase endlessly and these profits will increase more as the bitcoin make new high over the years.
I agree with you. It might be a good move for an investor to focus on the number of Bitcoins or Satoshis instead of the price of Bitcoin. Our goal is not a price, but the number of Bitcoins. So while accumulating Bitcoin, we should see Bitcoin as equivalent to fiat. That is, not the price of Bitcoin, but the number of Bitcoins.
Then maybe we will get some relief from the volatility of Bitcoin prices and the market volatility will not affect us in any way. Maybe it will be better for us to hide the price of Bitcoin and show the number of Bitcoins. Then maybe we can focus more on accumulating Bitcoins than on Bitcoin prices. This can be more effective for accumulating Bitcoins.
