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
It really might be that we will not see any current altcoins , probably eth will stay for sure - too much money has been put in it ,and if vitalik is safe and sound eth will prosper. It looks like there will still be doge coin , and some from the old school
