Old tv got bustes but the speakers are really good and I want to salvage them.
I did some research how to diy stuff like this but I dont know their wattage or Ohms. Nothing on them. Cant pry them open for more info and can't find anyhhing similar online from this brand to check.
These are about 20x5x5 cm size "Galax" speakers.
How do I not fry these? Will a cheap aliexpress 50+50 watt amplifier and 24 volt power supply will blow them?
I have never done anything like this before so Im not sure about the wattages and fire safety.

Which estimation could be considered more accurate?
Electricity price is intered as 0$ in both estimations

I would like to preface this by saying this is only for discussion and not intended as FUD. Maybe enen these analogies are too far fetched, but here goes nothing:
The did not watch the video summary: So the talk guest here is suggesting a satoshi price tag as a collateral for online identities to prevent spam. The idea is that even a minimal price on scammy or spammy behavior significantly reduces said behavior. Acting out or spaming makes you forfit the deposit creating the need for additional collateral deposit.
I see two problems here:
It popped for me that from certain perspectives, you can replace bitcoin with CBDC in his talk, and it fits perfectly for

EDIT: Without a node and only in windows
My assumption is that I can download a block, it's time stamp and the entire list of TXs and use comand line to hash it using sha256 algorithm and get the same 0000... hash thats on any explorer.
I checked blockchain com, mempool.space and a few other online blockchain viewers but I'm strugling to actualy find clean csv or smth to download that I could use for hashing.
Googling gives me some basic 101 on tx verification but not specifically what I need. Any one can guide me to the right direction?
I just want to ceck one hash out of curiosity.

I want to discuss a theory that it mightbe possible to intercept a new hash for the next block before it has been broadcasted to other nodes and thus - steal the block reward by broadcasting the hash faster.
When a miners hashing work has been done and a sufficient hash has been found it still has to be broadcasted online to claim the block reward.
What does the bitcoin network does to prevent that broadcasted data to be intercepted by a MitM attack?

TL:DR - Why is bitcoin mining actually difficult when hashing is inherently an easy computational task?When researching what bitcoin miners are hashing I always end up with the same result:
Miners take the blocks header, tx data, nonce and guess a hash with a specific amount of zeroes in front of a hash according to a predetermined difficulty. The result is proof that work has been spent to get the hash to prove there was no cheating.
But from experience, I know that hashing data is inherently a fairly easy computing process. You can do it on literally any device (even with pen and paper), you just open any command line, take any piece of data and apply a SHA-256 algorithm and you get a

So the Freedom Convoy news kinda dwindled down and I decided to look up how it ended.
Turns out Trudeau got sick of it and ordered police to use gas and arrest everyone aaaand wait for it, blacklist crypto addresses from local exchanges associated with the bitcoin donations.
So the donation address distributed funds to other addresses to the truck drivers in the very emotional and inspirational video and now those addresses are blacklisted from all local exchanges.
Theoretically, a person can just send some/all funds to another address and avoid the blacklisting of that address?
OR, is the whole future chain of transactions are blacklisted?

Risks of adjusting gas fees manually on beefy, avalanche, metamask
reddit.com/r/BeefyFinanceBIFI/comments/qwrhze...10
Avalanche gas tracker shows current gas fees about 25-30 gwei but metamask sets up over 60gwei.
Is it safe to lower it manually to about 20-25 when withdrawing or depositing funds?

Does anyone know if Polygon network withdrawals are working? this warning message is kinda confusing.

Anyone knows what would be the fee for a wire transfers from europe?
