Guys, you gotta do proper research before investing in an altcoin. I'm seeing many people promoting their coins with just qualitative reasons. Check on the development of the coin, check on the community, check on trading volume and of course market cap. You might want to use a website like
coingecko for research.
For me, If I'm planning on holding a coin I'll do a large amount of research - check full price and volume history of the coin, dev team, release history, press releases, news, scam accusations, check for premine, number of posts on here. If I'm only trading for a few weeks for speculation - or its a long established coin, then I'll just check the price history on CMC and a small amount of fundamental analysis.
