Well dev if only a few people hold it, then it is very easy to relaunch the coin. You only give the current holders their equivalent of the new coin in marketcap or even less like 5%. What you could do is first develop something that is Chess related for example a coin that pays winners of tournaments on LiChess using Blackcoins custom mining. Or maybe it pays users involved in matches with each other, paying the winner aka fair gambling. The users can name their account off their public key. Users who gamble have their coins frozen for the duration of their match until a winner emerges by either registering the address before each game or putting it in a joint account. You can also do double deposit escrow between gamblers. Or you can rent out the mining power in Boinc project where miners run Stockfish which is open source. Strong Chess players might pay the miners to rent the Stockfish engine. Or you can try to solve 8 man tablebases using mining power. That will definitely draw attention. It all depends on your skill as a dev. Instead of launching a coin and then developing, develop something and then launch. Don't launch without a project in hand. That is exactly what crypto community is tired of. Nobody wants empty promise. Do first, talk later. I taught myself Python in 3 months and coded BitHalos prototype in 3 months 4 years ago because I knew how important double deposit escrow was to crypto. No talk only action. If I can do it, so can you.
