Better then real money? Of course yes.But the best in all cryptocurrency ? No.I think that better payment system is eth.
No i don't think so there are some altcoins out there that cheaper and faster than etherum but if you say etherum is better than bitcoin i might agree with you.
A good payment system should be faster and cheaper unfortunately you can't find those things on bitcoin. The highest fee and low confirmation are serious problems right now and this should be addressed immediately however if we compare bitcoin to other payment systems like PayPal or WU bitcoin is still the best.
Unlike traditional payment system services, Bitcoin is incredibly well. It is because it will process faster and transaction fees are cheaper. Being Bitcoin holders, payments can be made in the top of your fingertips.
