DislikedEDIT: only thing I can add is that by withdrawing money I DON'T increase the probability of a failure. Won't explain why - was already done before me - not on the example of withdrawing, anyway, if can't find google a little.Ignored
It is a relative probability, the more times you do something the bigger the chances that they will happen.
If you can achieve another 500k from the 500k in 50 trades,by withdrawing 250k and leaving only 250k in your account you have to take 75 steps.
Therefore increasing your exposure to the risk.So chances are higher that you`ll lose that 250k than you win another 750k.
But if you'd have 500k you have a bigger chance of getting another 500k than from the previous example 750k its logical.
Of course in the first way you'd have 250k secured. And lost the other 250k, that would be still a 250% growth starting from 100k
But in the second example youd have 1000000, from the initial 100k that would be 1000% growth.
