this question seems to be odd but from a tax perspective it is not at all; There are some rules for taxing in my location;
a) buy a coin - if you let it untouched (no selling) for 356days+ you have then not to pay taxes at all! which is very good!!!
b) if a coin supports interests - and here smartrewards come into play - tax free selling is only after a period of 10 years!!!
So I have know SmartCash in my local wallet and beyond 1000 coins your are in the SmartReward Game but then also in the 10 year taxing game.
Is there a way to reject/disable SmartRewards for an address for that reason?
Currently I think no - only choicees I had
a) put back to exchange : not a good idea
b) divide all amount of coins into pieces < 1000
For taxing reason an option would be fine to disable Smart Rewards for an address
