What is the area of bitcoin that is most in need of funding?

If you had a choice between an Ark wallet, a Spark wallet, a Cashu wallet, and a fresh regular lightning wallet, which one are you spinning up next?

the trend towards miner centralization does seem worrisome. what gives you hope on this front?

Do you think there is much individuals can do about this? for instance does home mining make a dent in miner centralization?

I read things about Ant Pool and Friends and Foundry getting seven blocks in a row. How big a problem is miner centralization in Bitcoin? Are we at red alert stage yet or just it's a concern but not something to lose sleep over?
