The problem is that, in my view, in order for a coin to be successful and usable, it must be efficiently, quickly, and freely tradeable. Peercoin is available to trade on several exchanges, however, throughout my experience, it has been very difficult to obtain due to poor performances by a third party. Their speed is terrible, their user interface is terrible, and frankly, many are dishonest with their customers. Coinbase is okay, however, they have a very limited selection of cryptocurrency to trade. I therefore have to buy Bitcoin or Ethereum with my US Dollars on Coinbase (for a fee), transfer that currency over to another exchange that supports PPC (for a fee), wait until a trade is complete, and then finally withdraw the PPC to my Peercoin wallet (for a fee) which doesn’t always work due to “system maintenance.” It’s a long, time-consuming, and frankly EXPENSIVE process.
There are some online DEX out there. @fishb0ne thank you for the reference, but unfortunately, I would be violating its Terms if I used its service (since I am a U.S. citizen), it doesn’t accept US Dollars as an initial payment method (i.e. I need to exchange crypto for crypto), and its interface has a time limit. Bitsquare (Bisq) is a DEX that doesn’t have those limitations, although it is admittedly slow and doesn’t support Peercoin at the moment. An approach that would allow a more direct exchange across currencies in a decentralized environment could be an even greater incentive for people to get started in crypto.
