People may learn but what about the cryptocurrencies charging exuberant fees to transfer funds? Many would rather deal with banking headaches than losing their money for using a service. For example, my household conducts 200 transactions a month, easily. If I were to use BTC for those transactions that would be almost $375 a month in transaction fees alone with the average price per transaction of BTC today. There is no way a service could ever become mainstream with fees like that.
Additionally, that is an unethical amount to charge someone. We complain about fees from banks, but you know how much my bank charges me for those transactions to include the monthly fee for my bank account? $0. Who looks more unethical in this example? Doesn't this go against EVERYTHING BTC was founded on?
