I hath 30 bitcoins at the moment is that a good all round figure?? I wold of liked to have around 300, however...
I'm considering dumping all that and investing in a cheaper alt coin Peercoin because of Proof of stake it operates greener than bitcoin.
I don't want to go half and half its either all or none.
Peercoin price is at 1$ I'm not sure on the math but I suspect Peercoin is better for me I already hath 800PPC right now but I'm not sure if I should go all in to 11000 PPC and if the price of PPC goes up to 50$ or more the benefits would be huge I'm torn to shreds I can't stop thinking about it.
plus I hath x2[Antminer S1] running 24/7 I can get about 2-3 PPCs a day Bitcoin isn't worth mining anymore wots the incentive?
wot should i do?

Why all or nothing?
In this particular case, it does not make any financial sense. If you want to support PC buy some and use some. But to go in like this -- well, i don't think it would be wise.
Why not play the arbitrage game instead. Invest some of your bitcoins in an exchange and see where that takes you -- and only buy and sell alts you want to support... even if you lose its a better state of affairs if your main concern -- money aside -- is being green...
