Yo @yukiame In today's real world of finances the cryptocurrencies have a scalability problem:
REAL WORLD:
Paypal manages 193 transactions per second
Visa manages 1667 transactions per second,
FUNNY MONEY:
Ethereum does 20 transactions per second.
Bitcoin manages 7 transactions per second.
Pay the lowest possible transaction fees, then you will have to wait for a median time of 13 mins for transactions to go through.
Folks bitch about someone writing a check in the queue.
