I believe there will not be any coins with a value higher than Bitcoin in the future! Without analyzing technology, we need to know that Bitcoin is now an asset with the same mechanism as Gold and even the supply must decrease every 4 years.

The special thing here is that no one develops or runs Bitcoin, and it's as rare as Gold. But the major investment funds in the world have to pour money into assets that help them reduce inflation or keep value for money for each year so that they do not suffer losses. And Bitcoin has enough demand for that. Therefore, the value of Bitcoin will increase and will not be reduced even if there is a big dump coming.
