You being new crypto world, I suggest you only to invest in Bitcoin & ETH
All other coins have a lot of volatility and manipulated by whales. First, try to do some research about the crypto market, see price charts of various coins and observe their movement. These are some other coins which I personally like to trade are LTC, XMR, ADA, EOS and LINK. But when it comes to HOLDING I just believe in BTC. All other coins are good to trade but not worth holding for the long term. So, if you just like to invest, go only for BTC only.
