Trades don't take place on the blockchain, instead majority of bitcoin trading takes place on centralized exchanges. So instead of blockchain analysis you should ask a centralized exchange to give you access to their database so that you can analyze what everyone is doing. Obviously they won't do that.

What you see some people do (like the scam site known as whalealert) is looking at the transactions and whenever it suites their trading goals they release it as a whale selling or buying bitcoin. Obviously no-one can know what that transaction was. Even if you can say for sure that it was from or to an exchange you still can't know if it was a buy/sell.

1. How did you find yourself on the forum?
I was searching about bitcoin and kept seeing bitcointalk links among the results. Naturally I signed up.

2.  In one word, sum up your personality.
Curious!

3. What is the underlying message of your personal text?
It [Beware of Greeks bearing gifts!] is referring to the repeating cases where certain people start praising bitcoin to gain some popularity in "bitcoin media" then use that popularity for personal gain.
The accompanying avatar portraying  McAfee and Musk with a Trojan horse is for extra clarification.

4. Aside from personal text, what other methods do you use to motivate people on this forum?
My posts (hopefully).
I usually use the personal text for something fun or a short sentence that I read in a book and like.

5. Do you think you'll still be a member of the forum in the next five years? (If not, what are the reasons?)
Definitely. Assuming I survive Corona virus which I'm currently recovering from.

6. On the forum, who inspires you the most and why?
There are so many, most of those participating in Development & Technical Discussion board.

7. What are three of your favorite bitcointalk topics?

8. Some experts predict that the price of bitcoin will reach $100,000 before the next halving. What are your thoughts on this, and do you believe this will happen before the next halving?
I've always said since this 4-year cycle has had first 3 years that were very similar to the first 3 years of the previous cycle, there is a good chance that the 4^th year be the same which means price should reach $500k as the peak of the next bubble.

9. One message to theymos
Thanks for maintaining this awesome platform.

10. One piece of advice to the OP?
Accumulate

I don't think we can consider bitcoin a safe haven because its price is too volatile and there can be long periods of downtrend like what we had in 2018. Otherwise bitcoin is an excellent currency because of all the reasons outlined in OP (decentralized, no need for third parties, censorship resistant, ...).

No, bitcoin can provide that not cryptocurrencies in general. In fact majority of altcoins are useless and will die long before we see another recession.

In my opinion a real "bullish news" is one that could increase the adoption of bitcoin, like something that would introduce bitcoin to more people such as Amazon or a big company with lots of customers staring to accept bitcoin payments.
A bitcoin exchange that already has its customers adding a new fiat deposit option for them is not going to introduce bitcoin to anyone new so it can't be considered a "bullish news", maybe considered a "hyped up news" at best.

Technically you don't have to do any of these. There is even an option in the version message called "relay" that could be used to tell other peers you don't want to relay anything such as new (mempool) translations. Your node can also be designed so that it never uploads any data such as blocks, etc. (anything except what is needed for communication).
There is no option for this behavior in reference implementation though.

A code running in your browser can not be as efficient as it is needed for mining a cryptocurrency ever. Besides, your browser should not even allow such scripts to run in first place and if it does you need to look for a plugin that prevents these things.
You need to find a miner (usually a desktop console app written in C/C++/Assembly) that is specialized to mine a certain altcoin using your GPU or CPU depending on the type of coin you want to mine. There are sites like https://whattomine.com/ that could help with that choice.

The main difference between a low marketcap coin and a high marketcap coin is that the former didn't have a good pumping team while the later did. Otherwise they both are created for the same pump and dump scheme and are only good for short term trading if you can handle the pump and dump's unpredictability to make some profit. In fact the low cap coins get bigger and faster pumps compared to big cap coins.
In other words as long as you don't "invest" in them you could be fine.

And once again the BIP is not supposed to explain everything, specially the basic stuff. For example it didn't explain how to do a Base58 encoding, you already knew that or if you didn't you sought the document explaining it somewhere else.
String normalization is the same. You should just google how it works, programming languages usually have an option to perform it easily for instance in c# we simply call an extension method called Normalize(mode).

Bitcoin fees are designed to work based on transaction size and not the amount. This can not change without changing everything else about bitcoin too (eg. change UTXO based to account base). Without making these fundamental changes you'd introduce easy attack vectors. For example I can create a single 4 MB weight transaction that has a small value and pays a small fee in order to fill a single block and continue that for every block.

That's the signs of centralization when there is a single entity controlling the majority of the hashrate it will obviously resist having its own blocks be reversed. So they still stick to their chain to keep their block rewards valid.
In any case, it's about time someone started having fun with this shitcoin.

There is no limit to what you use lightning network for and since many of the altcoins are copies of bitcoin they too support lightning network of their own. There is no centralization in bitcoin either so any transaction whether on-chain or on second layer would require a regular confirmation from any miner who picks up the transaction.

There is no bug in python, the bug is in your usage of AES. You are using one of the modes that does not encrypt each block individually so when you encrypt the first block (first 16 bytes) you get the correct result but when you encrypt the second block (second 16 bytes) you get the wrong result. Then you concatenate the two parts and encode it with base58 so your string ends up looking like that.
Use the mode I told you above (ECB) and it should fix your issue.
Learn about AES modes here: https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Electronic_codebook_(ECB)

You can see the data in your base58, the last part is the second block you encrypt which is different:

The correct term is "fiat" not money.
Money is any object or verifiable record that is used for payment. So technically money is the bigger category that contains both fiat and bitcoin.

You are confusing negative news with FUD, not everything negative is FUD.
In simple terms FUD is the lies or false news that is being spread to cause Fear, Uncertainty and Doubt among bitcoin owners to fool them into making a bad decision and sell their bitcoins to the market manipulators.
Assuming this news is not a lie, it is simply a negative news and not a big one at that.

It's usually because of supply and demand.
The non-KYC methods of buying bitcoin are usually rarer and harder to come by so when there is a handful of offers they can ask for any price they want and that creates a higher premium.
I don't think arbitrage is that profitable otherwise traders would have done it and brought down the price to what we see on centralized KYC exchanges.

These days it seems like the definition is same as someone who can create a shittoken so the later definition sometimes is used to defined a "blockchain developer" which is wrong in my opinion. A "blockchain developer" should be someone who is familiar with the blockchain technology not just know how to create a garbage. It doesn't necessarily have to mean someone who is an expert in cryptography but they have to have some basic understanding.

That's more like "contributor".

Were they ever banned?
As I remember Google (alongside a lot of other services) banned advertisement of scams including the ICO and all the alternative names for token scams, cloud mining scams, malwares disguised as wallets, pump and dump groups, ... Any legitimate business could still advertise.

A bitcoin compressed private key encoded as base58 has 52 characters, missing 29 of it means you are missing more than half of the private key which is 2¹²⁸ bits and is going to be impossible to brute force. Not only GPU but even with a specialized ASIC you won't be able to find this.

Could you tell us how you came by this private key?

There has been multiple cases where the shittoken creators offered their garbage token in exchange for bitcoin testnet coins and newbies started draining the faucets hoping the shittoken could gain some value when it was listed for exchange.

Technically since BIP38 is just using a couple of other functions you don't need the intermediary values for each step, the initial input and final output are more than enough. This is also why there aren't that many test vectors either.

But you can always create your own test vectors if you like, just take any of the existing implementations that is tested and add break points at different lines or print the values if the language has that option, then use those values.
