Thanks for all the responses...
Of course not, new not always good but old coin always have hope. Right now invest/ trade can bring loss but I believe many people still try to find strategy to keep get income, mostly use old coins. Which strategy success we don't know but never give up is more than worth.
We have thousands of altcoins and only some are profitable and established so why settle for less if we can pick those that can give a sure profit. You should observe how those ico tokens getting dump in the market even those promising projects become worthless.
