Dislikedwith 8% a month and in 10 yrs you can get (1+8%)^120 which will make your acc 10k time of what it is now.
in 50 yrs will get
10k*10k*10k*10k*10k times of what it is now.

I think it's a matter of time before there is no more money you can earn coz rest of the market no longer lose as much as you can earn.Ignored
you are always limited by liquidity pools...
8% a month is achievable, also 16% if you double your risk or 24% if you trade on 3% risk per trade.
BUT on the long run, you can't be risking 3% anymore, because the 3% risk of a big account, and maybe a 15 pip stoploss equals to an enormous contract size, and you have to wait some time to get the order done....
so maybe you can trade a little longer if your system is long term, but on the short term, you are limited.
ANOTHER BUT:
I think in time what will change is what i call spendibility...
What i mean is if your account is large enough, even 3% a month can guarantee you a great living. so you don't need to squeeze your trading to gain so much more... you just need to earn more than banks, or simply retire and let the banks do your job.
so your limit case won't ever happen, because you will stop yourself way before reaching problems with order send due to volume.
