It is not bad to KYC (though I wish it wasn't necessary) if looking to get more involved, as I think many projects will require it anyway. 20 SPS a week is a decent trickle into other coins too :)

I am not sure about all of the DEC rewards now in SL - though I think they pay it in credits instead. I don't know what the limits are or what cards are needed etc to do okay in each league.
