Which altcoins do you think will see year 2020 with prosperity and why they will survive?
I think following will be there
1) Ripple / because of its application in banking use
2) Ether / because its smart contracts and scripting functionality
3) Dash / Instant send and private send
We dont know what will happen in 2020 or if its still exist. We dont know. But as I saw the list of the altcoins, I think ethereum will still on the list after 2020.
