Like I told you in PM. It is not the right time to invest.

The price of BTC is going up after the little crash.

Best thing to do (that's what I am doing but you do what you want) :
Buy BTC (with €) -> Buy LTC (with BTC) at 0.03 -> Sell LTC (for BTC)at 0.04 -> Sell BTC at 1000€/BTC (and above)

That way you can almost double your investment in 2-4 weeks.

When my trade is done I can invest 10-20 BTC so you can do whatever you want.

Do you know about watercooling ? It is very effective if you consider multiple big double GPU like 5 x HD7990 in the same circuit.
