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
I hope this happened too in all coins and in bitcoin a sort of upgrade in the system of bitcoin will be the best of opportunities in the coming year 2020 the price value i guess will increase in a high rate at this time so i hope bitcoin get dump soon.
