Maybe a more realistic question: what would stop average people from using bitcoin.

Corporate
1.  Banks and Corporations buy up the majority of bitcoins driving the price higher that the majority can afford.
2.  The Bitcoin devs limit the onchain transaction capacity causing the transaction fees to be unaffordable compared to all alternatives such as offchain networks and altcoins or even the normal fiat banking system. Making sure only the elite rich transact in bitcoin.

So you are against Bitcoin am I right?

Decentralized.
Anyone is allowed to run their own node, with no permissions. The network works peer-to-peerly and thus, there's no border to "stop" it. There's nothing to be "stopped", only nodes communicating with each other through the TCP/IP protocol.

Censorship-resistant.
Since it's decentralized, there is no authority to freeze a transaction, which makes bitcoin censorship resistant to anyone who could govern the way money circulates. This frees people.

Bitcoin is not only a “currency”, or some consider a “commodity”, it’s a censorship resistant, multi-generational protocol too. The market can be stopped, but Bitcoin goes somewhere it can find efficiency and flourish.

Overestimated. Ignore.

You left out a line of pseudo-code:

It should be:

For i = 1 to N
W_t = {
    M_tⁱ  (when 0 ≤ t ≤ 15)
    ROTL¹ (Wt−3 ⊕ Wt−8 ⊕ Wt−14 ⊕ Wt−16) (when 16 ≤ t ≤ 79)
}


N is the number of blocks in the padded message, so the first line says to loop through all the blocks in the message (this explains where the ⁱ in the M_tⁱ comes from).

W_t is the t^th word of the message schedule, so when processing word #1, that would be W₁, when processing word #2, it would be W₂, and so on.

For each word of the message schedule, you perform one of two processes...

If you are processing any of the first 16 words in a message block (word #0 through word #15), then you simply set W_t to the value of that word:
M_tⁱ is just the t^th word of the i^th message block

If you are processing any of the remaining words in a message block (word #16 through word #79) then you set W_t to the result of the following function:
ROTL¹ (W_t−3 ⊕ W_t−8 ⊕ W_t−14 ⊕ W_t−16)

ROTL¹ means to perform a one bit circular left shift.

The thing that is being shifted is the result of:
W_t−3 ⊕ W_t−8 ⊕ W_t−14 ⊕ W_t−16

Remember that you are processing the t^th word and that this only happens when you are processing words 16 through 79, so for example:
If t is 17 then you perform:
W₁₇₋₃ ⊕ W₁₇₋₈ ⊕ W₁₇₋₁₄ ⊕ W₁₇₋₁₆
complete those subtractions and you find that you are performing:
W₁₄ ⊕ W₉ ⊕ W₃ ⊕ W₁
Since  is the symbol for the EXCLUSIVE OR (XOR) operation, you need to perform an XOR on those 4 words of the message schedule.

This set of instructions is performed for all 80 words in the message block (word #0 through word #79)

Don't expect that you can buy bitcoin with $50 bitcoin will never get back to that price its impossible to happen right now if you can realize and think deeply who those support bitcoin and there are countries that bitcoin are accepting and you don't realize many business online are accepting bitcoin?
and many people are using bitcoin so its impossible bitcoin price will drop at that price.. And i think devs are holding a funds to support bitcoin when never the price is drop below 2k look at the fluctuate there are someone are sill supporting bitcoin just to stay the price at 2k value..

Thank you for the straight forward replies

@alani The news are so negative right now. They're scaring away all the newcomers. This is why such a small percent use cryptocurrencies...

@boyptc Gut feel, yeah, I can't rely on mine. I'm not in for a long time. But for example, when NMR reached $100, one guy on discord said "there will be one more hump to $130-150 then it will dump" - It happened! I know, everyone is saying something and it can be only luck or coincidence. But he said he knows how to recognize the P&D, and the pattern applies. Looking for a pattern :\

@socks From what I heard, whales can't manipulate btc so easy. At least not as easy as they're doing with alts. I don't think will get any positive news on btc any time soon^^
