•Will the value remain?
For example
I got a Klarity token and I got no gas so I will leave it there for a year or two.
•Any chances of value getting higher? Or it will die to years later?
for token, I think few token can survive more than 1 -3 year, but any token just life for several month.
if developer still active, and still on roadmap, I think it will survive for several year.
but if u r decide to hold coin may be it will different ,
because mining and development still running, and miner,comunity will always support their coin,
adding new market, publish, and many more
