I getting the feeling that bitcoin would not retain its position if the defi and yield farming continues. This new concept of mining has an easy way than a regular mining via equipment so probably there are miners who knows how to trade will be interested with these kind of business.

Considering eth will shift to PoS isnt it convenient when they already there? The only choice of miners is to find a new coin to mine or shift to a different approach of farming which is we know gave a lot of profits.
