I think the best thing to describe this is to not invest in shit coins, You should study or do research when you are going to invest in a token or an ICO. Most of the tokens in the market are shit coins because they were just thousands of cryptocurrency in the market which dividing the demand of the community in a token. If you are going to invest in a token that has a shitty team or developer you might just end up investing in a shit token these coins might not even reach the market.
Sure. Without research, investing in Altcoins is risky gambling.
There's a famous term: "DYOR"

Research, that people are collecting all facts, what they are buying. It's quite possible to detect a good altcoin when it's still very unknown but that requires a deep research and much experience to know what's important to detect promising Altcoins. For Newbies, I won't recommend that but if one knows the market, it could bring some profits. Same for trading, only few, experienced traders are making profits, most of them lose long-term.
