do you think their technological potential will be able to survive the next trend? How strongly people value technology over speculation in 2021.
Don't overcomplicate it, OP.
As long as whatever the project you are thinking of is still needed these days, it will still survive on whatever trend arrives. I won't bother looking on what coins or "ecosystems" are those you mentioned, but just take my point.
For me, every ecosystem project in the future will certainly follow the current trend, however their technology will definitely continue to develop due to updates from time to time, if we compare survival with bears, their project will definitely survive.
Currently the project still needs a new ecosystem to start the trend.
For the OP it's too complicated to do this speculation because for me every big project will definitely do with the goals of their respective roadmaps.
