so who and when will solve that problem?
btc transaction fees are way too high!
btc transactions are way too slow!
as im the big fan of fiat money and banks and reason for that becouse i make my transaction with online bank much faster to same bank and with much less fees then i do it with cryptocurrency.
the cost of something what is so hovest should be cheap as possible is way too high and ethereum is expensive too but at least eth transactions are much more faster so you get what you pay for at least but bitcoin it need to improve much more
The issue is real so there's no denying! Bitcoin scaling is an issue in reality but there are certain measures in place like Segwit and another much impactful measure in on its way - Lightening Network!
So what we all face today will be eliminated eventually. There are still bugs and vulnerabilities in LN but every new technology faces such issues. Once LN will be up in full scale and with all vulnerabilities solved, bitcoin will surely become the most preferred choice among the cryptocurrencies for transactions.
Also don't compare fiat with bitcoin because an age old system can't be really compared to an 11 years old system.
