Transaction using VISA is very conventional and out dated
sure its conventional and that what makes visa more acceptable than crypto or lightning network . visa isnt also out dated if its outdated then why we still see it everywhere ?
while virtual money such as bitcoin provide more advantages so buyer and seller don't need to spend much time and money for their transactions.
when using bitcoin people spend fees and they also wait for the transaction to be mined while using a visa/credit card are instant . no fees , no waiting time .
The improvement in technology such as this lightning networks should bring advantages to people and make them leave old way of transferring money.
thats impossible . some will stick on the old way of paying because crypto is too complex for them . though this lightning network is a good implementation to speed up the crypto processing time .
