I open this topic because i want know the opinion of others and also to help other to decide
OK... I will give you the list of 5 altcoins, which are having the maximum future potential. The list is in decreasing order of potential.
1. Bitcoin Cash
2. Ethereum
3. Monero
4. Waves
5. Litecoin
I don't know much about Bitcoin Gold, and therefore I am not including it here. My opinion may change after its listing.
