How can one create a valuable altcoin without conducting ICO in 2019-2020?
The main objective of the coin is for me one way to create a valuable altcoin.
To be honest, I don't see any altcoin right now that became successful without launching an ICO or even an IEO (if there are some that you know then you can share it here) so launching a coin without an ICO and hoping it to become a successful one is very hard even though the objectives of your altcoin is very helpful to the people.
ICO is another way of marketing the coin so if you don't conduct an ICO, you should think of another way to market your coin aside from conducting an ICO.
