I don't know much about how BTC or ETH works, but why all cryptocurrencies takes so long to confirm a transaction. I think even 30s is too long, why cant it be instant like PayPal?
Unlike other i guess sending money would not be easy unlike in bitcoin it is a new kind of technology that you can send money with bitcoin i guess it is really the most popular currency but we all know because of its popularity a lot of people use where the bitcoin cannot handle so the transaction become slower.
