but back to the project, there are a number of ways to ensure the longevity of the city. To maintain the presence of the bitcoin, you could invite bitcoin related companies/enterprises to operate there , create something you can't have in an established city, even if its abandoned but to be honest the only abandoned cities you're going to find are pre 21st century towns in the center of nowhere, it wouldnt really save you an awful lot of money because you still have to add infrastructure, modern sewage processing, storm water pits/piping, electricity generation/connection ,etc .
Then theres the dilemma of internet. buildings are cheap, its what makes a building habitable that actually costs money.
i can tell you now if you refit an old town its going to cost you alot more unless you are incredibly lucky and find a place that has everything already in place and its merely cosmetic work required.
you are now boring the community...
1. the town you live in now, infact the towns anyone reading this lives in now.. it has internet correct? it has shops? running water? electricity? it has warehouses, office blocks, apartment complexes, houses, etc??
so its cheaper to bribe every business in your town to b bitcoin friendly, as oppose to building a city and then trying to get businesses to go there.
2. do you even know the cost of one skyscaper... the cost of 1 apartment block. the cost of one house.. screw it lets keep it simple
a city has a million population. so imagine 1 million houses.. do the maths.. building a city costs more then the total market cap of bitcoin.
3. yea you want to build it. you say you dont want to manage the funds.. i hear you.. you want a middle man to hold the funds for a little while and then give the funds to you.. oh wait.. that still means that you want money.... i see now, and let me guess you want all the blame to b shifted back on the middleman for being a bad escrow... i totally get it now.
4. if you were in the mindset of expanding bitcoin you would be trying to get businesses of the world to accept bitcoin, but no all you want is for the community to give you a wage. even with your weak concept of what is actually required to build a city. you have no clue!
now move on back to your cave or atleast try getting businesses in your town to accept bitcoin. video it. then show us you working on a construction site. yes video yourself doing some actual work.. oh wait you wont do that.. so i guess the only option is going into your cave
