thinking of buying a bit, selling idea did not even cross my mind.
however, i think that you guys are wrong about the defi idea.
Mind you, the current crop is unimpressive, but so were excite, lycos and infoseek before google showed up in search.
Defi is inevitable, the question is only who the 1000 pound gorilla would be and which network would host it.
If you know of an app on btc that could do de-fi, speak out. There are some wallets, maybe Liquid, not much else (so far).
Cough-ethereum-cough is in the early lead, but it could be meaningless as we are talking about 4-7 bil out of 100 tril or so deployed there so far.
Plenty of time for btc to show its dominance in that area or leave it for some newcomer.
Eth cannot do defi because fees are too high, negating any reasonable tx, hence the recent crash.
Personally I have a problem with the mere concept of Defi. I don't see finance and decentralization going together. I see why it would attract some people, but I also see how governments are going to be all over it. I don't really see a use case either, but then again I live in a country where we don't have credit cards but debit ones. And there is no such thing as a credit score, or "refinancing", the less bank credits/mortgages you have the better.
defi (without idiotic 'yield farming') is just another term for automatic financing sans banks.
You have capital, you can lend it out on the blockchain that is able to employ smart contracts (be it at the core , in L2 or L3) and get interest.
Capital has to move, simple saving is insufficient for the advanced civilization to work.
Deployment could be automatic (on the blockchain like bitcoin) and highly effective.
Banks are less needed in defi world, hence no Cantillon effect and no pernicious brrr.
Poopooing defi will not be in bitcoin interest. Figuring out how to do it apart from essentially giving your coins to blockfi or Celsius and rely on their good graces might be important.
Governments have nothing to fear as taxing could be programmed in, if needed, not sure why they would be 'all over it'. They won't be, IMHO.
Why sell your btc when the time comes when you can use it more intelligently?
... Also a few days ago or something like that there was some kind of study or counting that the seasonal Flu has dropped 300-400 times or more in some parts of the world.
