Not all new coins are profitable because most new coins fail, or some become a scam. I think to take the safe way is an old coin because the old coins most of the projects are already running this can make old coins make profits in the future
yes, indeed all new altcoins may not be able to make a profit, but there are also many new altcoins that can generate profits, so that everything can happen, but to choose to buy to invest or trade all the options within us that can determine all that, and big or small profits, of course, from our own speculations and predictions.
In crypto everything will be determined by how good that ico is. As far as i know even if you are speculating on the big market but if that was not a good coin and that will never give any impact. We know that the price of altcoin is following the update that will come from the developers. that's the rule in crypto.
