Some people call it another scam. But during the days when Ethereum blockchain started ERC20 and ERC721 (NFTs), some people were saying that it is the beginning of scam. Yes many people were scammed and many people lost money, but there are many of these altcoins tokens that are surving now.
The mempool is far from getting less congested. Bitcoin transaction fee is too much and becoming unbearable.
What do you think can solve what is happening? How can the mempool become not congested again. More miners needed or what?
I believe consensus rules are being exploited now.
At some point the network will be forked with new consensus rules which will not allow those ordinals to do that , which are only spamming the bitocin network.
Everything will be back to normal. There is not need to panic, imo.
