it may be active now but it was inactive for a long time if most people have never heard of it and most exchanges (I want to say all but let us just say it could be listed somewhere now) do not have it.
This is not necessarily true. I don't know about Devcoin's history, but Peercoin (the first PoS coin) turns 9 years old tomorrow. The only reason Peercoin is not on a lot of exchanges is because centralized exchanges and services charge exorbitant sums of money for listings. Being a decentralized project with no way (or desire) to print new funds into existence, it can only function through voluntary donations, which is difficult to raise for listing fees in the hundreds of thousands or millions.
I would recommend that Devcoin move toward developing trading support for decentralized exchanges like Peercoin is doing to get around the walled gardens. We're developing wrapped token functionality so trading can be done through Binance Smart Chain and Ethereum on popular DEXes like Pancake Swap and Uniswap. Entry to these markets are permissionless and only depend on the talent of the dev team for integration.
