The whole point of cryptocurrency was it was supposed to be able to help the poor and middle class move money without having to pay ridiculous taxes and transfer fees.
As some one who was actually a very big part of the very first altcoin and many of the followers, that is not why they were developed.
OK fine, its why bitcoin was invented. And it was certainly a potential selling point, but its not any more.
yes, peer to peer currencies (and btc wasn't the first), are designed simply to leave out the greedy none productive middleperson, money changes etc btc itself also to aid micro-transactions.
something completely lost to the current bitcoin developers
now their are tons of 'money changes' in crypto.....taking their cut no different from fiat.
as for helping the poor, well no matter what your poison when it comes to currency those rich in fiat will always be those rich in the new currency.
most the 'crypto' crowd these days is the 'get rich quick crowd'
