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
Probably Ether will stay in 2020. Ether is the second cryptocurrency that runs in our society. It is the second powerful coin. Etherium will last together with bitcoin. But I think if we are comparing these two coins, if you think that ether can beat bitcoin well it'll probably happen in the near future but it will take time. Bitcoin will stay in the top for the next years.
