If you are a beginner, then you do not need to trade anything except bitcoin. Experienced traders can determine the perspective of some coins and make trades with them because some altcoins look quite interesting in the long or medium term.
Just because an altcoin looks interesting does not mean its worth putting your money in. Where does the interest come from? Take every whitepaper and roadmap prepared with a large punch of salt (LOL).
Not only are they always misleading into investors trusting them but they will change them from time to time for their own benefit or delay releases just for the sake of it. If interest is coming from the price pump be very careful what coin you are jumping into because transient pump and dump are normally happening in every coin and they might wash you down during the dump.
Pumps and getting 100x-1000x possible profits is the main thing why most people do put money into these projects.Only a few do trust up on them when
it comes to longer prospects.
As an investor if you can able to risk your money to diversify out by either investing on ICO or directly trading them when it is already on exchangers.Its worthy but be careful on what you are dealing
because not all tokens do pump.
