Which old school cryptocurrency altcoins do you think still have big time potential? Some of the coins with major potential and expectations were power ledger and substratum. Do you think they will still achieve huge success or will the be displaced by similar cryptocurrencies that have entered the market after their introduction? Feel free to comment other oldies but goodies like Basic Attention Token which is on the potential list for addition to coinbase!!!
Ether, Bitcoin, Litecoin, Ripple I don't know about when they were invented and developed but I can say that those are the top coins that I have in my wallet and I have put My Hope On them as well as holding them.
