The dollar allocation solely depends on how much you want to allocate. I have no control over how much you decide to allocate.
This thread assumes no conflict of interest. By that I mean you and me are not big enough of a player to affect the market in a significant way.
It also does not affect you either whether I allocate 1% or 10% or 100% of my portfolio for the BTC/USD trade.
There is no promise that the analysis will be correct, so you get the analysis as is.
Winrate and RR are important. In the ideal world, you win 100% and it is optimal to throw 100% of your portfolio to trade every time.
However, that world is probably a pipe dream.
The dollar allocation doesn't matter, I agree. Hence I suggested percentage of bankroll. It affects you, because it shows whether you are profitable or not. Anyone can show 80% win rate. Not anyone can show 1% profit over 1 year.
It's the same in gambling, I always think people get fooled by 80% win rate 'tipsters'. Anyone can bet 10 times on 1.01x outcome to get 90% win rate.
The ideal is not 100% portfolio on one bet lol. That is NOT the real world

My winrate from the past few years has been around 35-40%.
Daily Timeframe is a bit higher at 4x%.
R:R 3+
I do not claim higher winrate than this, so you can adjust your expectation as such.
At the end of the day, it's the ratio between R:R and winrate that pay
