Lol new price on bitmain is 0,36BTC, so 0.5BTC is kind of a rediculous price
Where did you find this price? I only found this one, with 0.406 BTC as a price.

(both are included, as the EU is a customs union) However, of course you aren't obliged to buy it, and 0.36 BTC sounds more ridiculous from my perspective than 0,5 BTC
P.S. Lowered the price to 0.4 BTC, which is still dirt cheap because of the improved ROI due to the BTC price hike. (assuming electricity costs are being paid in fiat currency)
