You can buy tons of stuff with Bitcoin (not just drugs). You can transfer it around the world basically for free (transaction fees amount to the equivalent of pennies no matter how much you send). It's immutable. Basically it does the things it's supposed to do. It's gained widespread adoption, a whole economy, thousands of businesses.
doesn't that describe a lot of cryptocurrencies? or are you suggesting the people in these regimes use cryptocurrencies as an intermediary to transfer their local currency into more stable foreign currency?
This reasoning is really strange and reeks of bitterness. Do you have anything backing up your claim BTC is used for mostly illegal activities? Please provide some very clear citations for that claim.
There are very few things you can buy more easily using Bitcoin. And average fees to send money right now with Bitcoin are 2-3%. Which is not great, considering the current financial system offers lots of much cheaper options for sending money.
So because Bitcoin hasn't overtaken fiat currency as the de facto international standard means it's a failure? All of the critics in this thread sure have some narrow goalposts, don't they?
It is, without a doubt, successful.
