Let's try a simple transaction of buying a cup of coffee at a store, how long will the shop owner wait until the transaction is completed and conformed? using Bitcoin, it will takes hours and using IONs it will take minutes...
A bitcoin transaction is broadcasted immediately and visible within seconds - so when selling a cup of coffee, nobody will wait for confirmations, because the risk is so small. You want to wait for confirmations when you sell a car or a house. Not with small payments. By the way, the confirmation of a credit card payment takes days. And vendors accept that risk, too.
Nobody needs ION or any other shitcoin for "faster confirmations". Bitcoin is fast enough already. And it will become even faster with Lightning. You can keep your ION scamcoin.
