I think you are fundamentally wrong in your estimations.
A return flight to krakow from london is around £40
you only need 150 more steem to purchase your steemfest ticket
accomdation is dirst cheap
with the time from now until November you would easily make the amount it will cost you in steem.
I wouldnt advice a big powerdown but I do think you have GROSSLY miss judged how much it will cost you buddy
:) rethink the cost my man and you'll realise you may need one weeks powerdown to get the steemfest ticket then the rest travel/accomodation youll earn way more than needed before novemeber :)
I see where you come from. But also around that time i need to travel to Portugal to see my family and thats why even if it is not a lot adding all together it is really risky. :(
But i totally know that it is not an expensive trip. It is just all the other factors around and happening at the same time :( but yeah now thay so many of you told how crazy it would be to power down i really know i cant use that as a solution lolol
