The other coins have failed because they failed as an investment tool, what they offered was simply in no demand.
What they offered was nothing, they only promised high tps blockchain without actually demonstrating that it has the claimed capacity while also remaining decentralized. And of course the developers never had interest in delivering, they already got filthy rich from their premine.
If there was a coin that had better scalability than Bitcoin without any downsides, it would have been still alive today at at least $2 or #3 spot and slowly replacing Bitcoin. But there is no such coin.
And this shows basically that the price is more important than usage, any normal business that would have experienced this type of congestion would be bankrupt, a bank raising the fees this much would be left with no customers, but since crypto on-chain usage is like 1% of the importance of trading and investing, here we are. And here we will be at the next spam wave since nothing is really being done.
That's a tough problem. The problem with all the digital money systems (both crypto and fiat) is that its highly dependent on data traffic volume and data processing power. So increasing number of NFT minters loads all the mining facilities, so that it becomes impossible to make transactions in time.
That's not how the network works, that's not how sanctions are being confirmed.
It takes a script that can run on a Pentium 1 to generate 10000 ordinals, it takes the same hashing power to create a block right now even if it's empty or it has 4000 transactions in it.
