That is just pure dumb in my opinion. I like bitcoin, but I am not planning my entire life on the viability of the matter.
I'd even say the guy accepting foodstamps with over $9,000 in bitcoins (more than double digits, price at $900 now) is a leech...
Be fair. $9000 is nothing and if Bitcoin carries on in 2014 as it has in 2013, that $9000 will be $270,000 which can take him out of poverty and off the welfare rolls forever.
9 grand is more than half of a minimum wage annual salary ($7.25, for 15k annually) and while I now see it as "nothing" it most certainly is not to people actually in need of financial assistance.
Regardless, someone could feed themselves without cashing out all of their BTC. Lets just say he sells one, $900 could feed someone for 4-6 months pretty easy. The remaining 9 coins are still worth $243,000 in your scenario.
I don't much think it's fair that this guy has the opportunity to potentially become a quarter-millionaire while on the government cheese. I could easily liquidate all that I own and go "bitcoin poor" foodstamps and all, probably be a billionaire next year (still assuming your crazy "bitcoin never stops exponentially growing" scenario) Is that fair?
