There is an exponential aspect to doubling.
In regards to bitcoin specifically, I would suggest anywhere between 1% and 25% for someone who is a responsible grownup.. so yeah, maybe banks have to work their lil selfies up towards the higher end of the range... .. but if they are actually contemplating shitcoins or "crypto" then fuck that nonsense, I am not even sure if 1% would be tolerable for that.. maybe 0.25% at most?... or maybe up to 1% of the bitcoin amount.
I do believe that this rally signals the 15.5K bottom, but I do not believe the market will just run away and leave me behind. Inflation or Recession or Both!?, these are the options people... but sure drain oil reserves to make CPI print look ok for a minute that'll save us! ... it's going to be a tough year for markets bitcoin included.
Does not mean that it is a good idea to short it when the BTC price is about 75% below the November 2021 top and also about 31% below the 200-week moving average. That does not seem to be very smart.. even if you might be able to keep doubling down on your dumb bet until we get to $50k.
I buy the dips and sell the rips, this is my contribution to price discovery

watching price and placing bets, doubling down, taking profits, cutting losses. Its fun.
come on you know you wana play

What you are describing doesn't make me too excited... but I do get excited about various BTC accumulation strategies that relate to attempts to long term invest into BTC.. that can evolve into maintenance and or liquidation strategies, but to me it sounds like you are in the habit of some form of gambling.. which call me a fud dud, but I do not get too excited in engaging in selling strategies that are used to accumulate more bitcoin, unless you have already reached a considerable level of profits.. so that may well not really be having a sell to accumulate more component, but instead a sell to insure against some downside risk.. and really not expecting to profit in great ways, even though if you follow my system long enough it does seem to have pretty high likelihoods of being profitable...
... and I am not even sure if I give too many shits about profitability measurements, especially in the short term.. but for me it provides a kinds of psychological and financial balancing that tends to be comfortable for me...which seems to be pretty profitable in terms of long term tendencies and that is likely because bitcoin has been profitable long term and likely these kinds of considerations would be applicable to some others as well,.... perhaps? perhaps? .. even if they may well not know it.. not that I am trying to sell anything or convince anyone to follow in my ways .. peeps can do what the fuck they want, and peeps should be employing their own due diligence and discretion within their own judgement of their circumstances, even though I have been sharing my ideas for free in this thread for almost 9 years... and sometimes they are not very smart ideas, either.. so up to uie poo-ie if you might find some value in my posts.. oh yeah and another thing is that I find value in my own posts.. so there is that angle too.. my motivations to post are not necessarily benevolent in their ways of getting me to sit down and tap out some word-salads.
I would hate to rely too much on that kind of a seemingly random indicator.
