I agree if you see the alternatives coins based on the short term investment (trading alternatives coins) but don't forget about the fundamental of aspects of alternatives coins, it will gives good information about the cryptocurrencies and i think it is important thing about the cryptocurrencies before we make investment in cryptocurrencies except the technical analysis to prediction of the price.
Alternative coins or altcoins in other word, are always good choices for long term investment, especially when investors jumped at them at the right period of nearly the end of crypto bearish market. Technical analysis and any kind of prediction should not be over-valued because most of altcoins don't have enough big daily volume, that in turn makes them very easily to be manipulated by whales. Moreover, altcoins might play important role as substitutes for bitcoin in daily transactions in the future due to their more flexibility, faster speed, and cheaper fees.
