I think bitcoiners should be more concerned with Bitcoin, not the whole industry that just uses Bitcoin for their (mostly) scam projects. The fact that someone who has been on the forum for years still thinks Kwon and his project aren’t completely scam doesn’t give me much hope when it comes to the future.
When you mention DeFi, what exactly are the benefits of something that generates a bunch of scams and results in financial losses measured in billions of $? This whole system is like a sieve through which someone pours water and expects that sieve to retain water, and we know that is impossible.

Do Kwon's acceptance of bitcoin into Terra's treasury was something no one in Defi was normally doing. No one in Defi cares about bitcoin. I reckon it would have more significance in Defi if Do Kwon used Ethereum, however, it would confirm that ETH as a better coin than Luna hehehehe.
Also, similar to anything in the cryptospace there will be many scams. If bitcoin had the ability for Defi projects to be built in the network, I am quite certain there would scams and poorly developed implementations also. However, calling all of them scams is wrong. Some of them are building the infrastructure for the future of the cryptospace.
