One of the biggest confusions about the SmartRewards program is about adding or taking away SmartCash tokens from the addresses.

You can add SmartCash to the snapshotted address and not lose your chance of getting a reward, but you can't take away from it.

Lets say you have 1000 smartcash in one address, you add 150 to it after the snapshot, so you have 1150, you will still get rewards, but if you take away 50 smart, you will lose your smart rewards, even though you put in 150 after the snapshot, because the 50 you took out is towards the 1000, not the 1150, its confusing but this needs to be elucidated better in the article, me doing so in the comments section is not the right place for it. This was meant to be just a brief explanation.
