There are two types of people that want to see bitcoin die. Those that missed the boat and are really annoyed about it, the others are government agencies who don't want bitcoin to compete with their local fiat currency
governments dont care. bitcoin is like apple iphones. it has no impact on minimum wage laws or tax laws or court fine rules.
all that occurs is when someone buys btc fiat moves from a buyers account to a sellers account. fiat is not destroyed. btc is just an asset.
(i have spoke to banks, government, economists and many others)
take for instance euro..
dollar doesnt care about euro because america ensures americans pay taxes in dollars thus keeping dollars in circulation.. same situation with btc.. until laws change where taxes are paid in btc and btc is used to pay public services where by the dollar is not needed. america dont care about btc impacting the dollar.
thats another failure of the devs. by not making BTC reliant on a fiat valuation.
if btc was instead measured on a labour valuation. EG 550minimum wage hours.. then you would see many people forex dollars to africa/india where 550 hours is cheaper then you would see an american buy 10btc via africa for the price of 1american direct btc. thus causing a landslide on thee forex markets between dollar and other currencies. but no. btc does not affect forex or fiat rules. so its not a big deal (a very big missed oppertunity)
