Not sure what you exactly mean.
Invest in projects with a solid roadmap, excellent team and a community and you will be fine.
If you throw money are pump and dump copycat shit coins you will loose in the long term
In fact you should just make sure that you'll invested on some existing project that proves that your money wouldn't be wasted. Some alts are just focusing on giving up value with their coin and don't even care about their project to continue in short it was all just imaginary that's why don't be surprised why those alts are all dead now.
I think otherwise. to hold would be great for the future for Altcoin itself because the level of security that is on Altcoin will increase with the running of the hold. therefore I strongly advise holding the Altcoin that you have for its security and its development to further increase.
