the problem with your logic is that you can not compare the profit on smaller amounts with the profit on larger amounts.
for example even in the real world you can turn $10 into $60 with a hundred different ways and they are all easy and fast and efficient.
but to turn $60,000 to $600,000 it is impossible to do so unless in some rare cases which you start a new business with it and your business is booming.
and it is the same with trading too, the volumes in many cases are simply not enough to support larger amount of money like 1000BTC profit in a short time.
