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.
To identify an altcoins is not too hard because they moving to one direction. Their growth is very slow and the effort of the developers is to advertise them instead of working on them (the projects) more so that people will use them (the projects) and advert the projects and not the founders advertising them. I have not even seen an altcoins forum where they can market their projects but instead.
Most of the altcoins failed because of improper planning of the founders. I don't normally like altcoins but planning to invest on two which I know that is good to invest.
