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.
Before buying some of these coins it's usually advised you DYOR first and if these coins are not listed on major exchange platforms then it's an indication you may be at your own risk , if they don't have a good community anda solid projects backing them, I think you should know what to do but then always know that on the long run the results will play out.
