If you're new and would like to invest some money into crypto currency I would suggest doing your own analysis on them.
Things like:
1. Reading about the coin you want to invest in online (check their website, idea, possible chances of success, check their ANN here on BCT etc.)
2. Check their ATH & ATL on coinmarketcap.com
3. Check to see if they are putting a good part of their money into marketing and PR services since this is very important to get the word out.
I have a few coins that I like and have invested in them like: IOTA, IOST, XVG, ETH, ETC you can check them out if you like.
I like your suggestion, to see the coin is good or not we have to watch it. don't easily believe what other people say. and additional if you are a beginner trader. better buy coins that have a large trading volume. because to avoid price manipulation.
