Ok thanks guys
100-150 per block sounds like the way to go then, and nearly 100%/year plus price inflation sounds pretty good to me - don't want to lose it all trading.  However with the distribution on Bittrex someone is accumulating big style atm so I think a pump may be incoming in the not too distant future.  Think I'll sit high enough up in the sell wall that if I get hit on a pump I'll be able to rebuy more afterwards (definitely want to keep GP for the future) - for a month or so & if I don't get hit on a pump I'll withdraw & stake.  Dangerous game but not as dangerous as dumping on the buy support and hoping price will go down again, got away with that once but price creeping up steadily now.
