Old coins perhaps have no chance of going into profit again
and thus will have the value if it is necessary to invest.
However, what we can only expect from it is when its value will
rise again in certain considerations and handful negotiations.
Some of the old coins are impossible to be profitable again because of the great coins in the present. But some are still having a potential to grow and rise again.
Yeah even though the possibility exists but it will certainly be a little risky. there are many more potential altcoin and more innovative, even more sophisticated ones. it's better that you choose and invest in the new coin rather than looking for potential in old coins that don't necessarily exist
