Another possibility, for several of us, could be to engage in a  kind of trickery in accounting and to cash out of BTC the amount that we invested, and in that regard, we are playing with house money, which is that we do not have any costs associated with the BTC that we hold.  Personally, I don't feel any kind of compelling reason to employ such a harsh strategy or cashing out in order to "play with house money" because 1) that would be valuing my wealth in fiat rather than bitcoin, 2) there are no real fundamental threats to bitcoin, even if the price may perhaps go down to below $3k.. perhaps?  Perhaps? and 3) Even if I am playing with both principle and interest, such practice gives me way more money to "play" with and it is like borrowing from myself to continue to use such value to invest in bitcoin (remembering one important principle that it takes money to make money and the rich get richer, which happens to be applicable to myself and to other BTC hodlers, especially referring to those who have been largely invested into BTC before 2017)
