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!!!
Power Ledger is not a concurrency. It is or utility token or a security. Probably a security since it started as ICO. Not sure what substratum is. I Also know that Power Ledger is from 2017. LOL how old school last year is.
There are lost of old real cryptocurencies. But only few of them have real world use case. One of them is Monero. Monero will always be used because it is fungible while Bitcoin is not. So coins will always stay side by side.
