I learned from pangolinminershop the base shop price is like 1.1k usd.
Some fees (like tax, shipping, etc ) might be added to.
On the other hand i don't know how about the warranty as it is 2nd hand.
Current BTC-Value is like 16.5k usd (+- as usual) so 0.1 btc is like 1650 usd and by so should cover the expenses to bring such a device to europe.
For legal/tax issues a bill containing vat is necessary in b2b; so the vat can be subtracted. other fees like tax etc can be used to reduce income-tax, so the price without bills would have to be lower, price with bills would be fair.
On the other hand the miner is in europe already and there is no delay. Current diff allows to min 0.00213419 BTC / day when wisely selecting the coin to mine on. When one is mining BTC, it would be like 0.00154383 BTC / day
Set this for 45 days (i do not think about difficulty-change here) we got something between 0,0695 and 0.96 btc without power-cost.
In Germany we pay like 35c/kwh, in other places electricity is cheaper. 45 days have 1080 hours. A device on 2kwh would use 2160 kWh which would in Germany cost 756 or currently 0.0458 btc.
My personal guess: Something around 0.15 btc would be a neutral price.
Did i miss something?
((for me: i would be interested too, but i need an official bill. if someone els would not, i can step back))
