I received three ordinal inscriptions in my bitcoin core wallet.
Since you posted this in Bitcoin Technical Support, you're going to get a Bitcoin based answer: there are no "ordinal inscriptions" in Bitcoin Core. If you have received Bitcoin, you can send Bitcoin.
Allow me to quote myself:
I've been wondering for a while what would be next after altcoins, ICOs, Forkcoins, DeFi and NFTs. I guess the next pyramid scheme is making up BS on the Bitcoin blockchain. As usual, a few people will get very rich out of this, and many people will lose money. All I can do is warn against it.
Do people not understand they need some centralized service to "use" their made-up tokens, which goes against everything Bitcoin stands for? So, when they think they have
this, in reality they have only
Bitcoin dust!
So , how do I properly send out an ordinal from bitcoin core.
If someone told you the Bitcoin dust in your wallet is "special", it's likely you fell for a (ponzi) scam.
