•What if I dont have any money ? And I decided to hold my altcoin at my wallet.
If you don't have money then how will you be able to buy the alt coin? You should first manage the funds that will get you tokens equivalent to your investment and the token value. You an hold the tokens as long as you want because it is digital algorithm and it doesn't have end. Its just bunch of codes, it won't die :-)
•Will the value remain?
The value remain
same if the development are not done for that token or the market capitalism doesn't increase or the investors are not there for it. The value will
decrease if the token is abandoned by the project manager/founder. The value will boost up if revers of above two things happen. :-)
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?
Well, nothing depends on the gas, it is only used for the transaction purpose and it is different in limits or different token.
