This depends on your port size/belief in your skill.
The question you should ask yourself instead should be, how many times can I try again if I have a drawdown.
If you have 10 sol, and you are aping 1 sol… you have about 9 trials (if you include gas fees)
If you can win 3-4 trades out of that 9, that means your port grows regardless (especially if you were quick to cut your losses for the other 5/6 bad trades).
