As an investor, i did a lots of invest in altcoins. Those were suppose to be good that time with having good hype, good team and community. But with having all of thats, most of altcoins scam after a time! I wonder for some altcoins, they were suppose not to be go but they scammed without any reason! And hundreds of altcoins are in my wallet, which are turn into dead shitcoin now.
You are not alone, I have a ton of tokens, of which a huge majority of the project is dead. However, understand the difference between shitcoins and scams. Shitcoins aren't always scams. It mostly happens to be shitcoin when the management fails at managing/implementing the project, or something takes away the utility of the token. Scam on the other hand could be you investing but never getting your capital or your supposed gain amount
