I'm looking for cheapest (in terms of user-to-user transaction cost) and fastest (in terms of transaction confirmation speed) blockchain protocol to develop my own custom cryptocurrency Token.
Could you advise me some of suitable protocols to look closely?
P.S. I'm in the beginning of studying blockchain technology.
Have a look on the waves platform. They are testing now Waves NG, which makes it the fastest blockhain platform in the world. BTC can handle around 3 transaction per second, Waves will be able to handle 100 per second. Also, on the waves platform it's very easy to create your own token for very low fees.
