My take on compounding is that it will only work on a winning system obviously.
If you have set your bank at 50 points then you will need to give it time to accumulate some profit – say 1 month (or 2 weeks) – and then adjust your stake (up) for another another month (or 2 weeks) and so on – still working on a 50 point bank.
The idea behind compounding is that you don’t withdraw profits (at least, not until you reach a max.stake you are comfortable with) and build your stake amount up.
Decreasing stakes is pointless – you are either going to blow the bank or find a winning method quick!!
