CSC doesn't dilute, the coins it stakes will stake the same and in fact more often the more coins CSC holds.
ARBX is having some issue that I think will be resolved if they get an update out this weekend for the bot. Its also that time of year when people walk away from the trading and get some fresh air, I expected may and likely june to be a bit slow for ARBX but it will pickup when the temperature does.
Thats enough of off topic'ish. Back on to REFCOIN.
