Before bitcoin cash hard fork, the issue was the fact that bitcoin cash community were demanding for block size to be increased which later led to hard fork that resulted into bitcoin cash creation. But, bitcoin community that see bitcoin as an asset still defended this fact and yet all the hard fork coins even after are nothing before bitcoin today. My opinion about bitcoin is that it is an appreciating asset, no need to increase the transaction fee because bitcoin itself will increase against fait in such a way miners will see mining profitable. If bitcoin possibly is increasing in value (price) which could also probably increase more in value (price) in later time, with the increase, it will be able to sustain miners to mine profitably. Only bitcoin to be an appreciative asset is enough for bitcoin to defend itself after all bitcoin are mined.

What I am trying to comment is the fact that bitcoin being an appreciative asset will make the mining fee to increase in fiat prices but not increasing in bitcoin itself. People that find it difficult to pay for onchain fee will later be resorting to lightning payment possibly.

This was anounced three day ago or so, if exchanges are adopting bitcoin lightning, it can be a great move towards lightning adoption generally. But we should still not to forget that this type of exchanges are custodial exchanges.

According to what I read on coindesk, I found it easy that to set up a lightning node will not be difficult. According to the write up, these are what needed:
 
The equipments
RaspiBlitz is specialized software that will automate many of the steps that go into creating our node, helping users to build their own. Once the node is all set up, the RaspiBlitz software will pull up a graphical interface for using the node – for making payments with it, for instance. Finally, RaspiBlitz also offers a set of detailed instructions, which we’re going to follow in this article to get our Bitcoin and Lighting nodes up and running.

The first step in building any Bitcoin node is to buy the equipment. Fulmo offers a package of this equipment for 269 euros (worth about $322 at time of writing). However, users can opt to buy their own pieces instead. The RaspiBlitz instructions suggest that users purchase the following:

A Raspberry Pi ($66 for version 4): This is a pocket-sized computer that powers the Lightning node. (Computers have certainly evolved since the ENIAC, which weighed 50 tons, about 10 times as much as an elephant.)

Power supply: USB-C, 5V, >=3A ($10)

Storage: A MicroSD card (~$10) for holding the RaspiBlitz software and a 1 terabyte SSD hard drive (~$100) for storing all the Bitcoin data. (Spoiler alert: There's a lot of data. And it'll grow if a node is up and running for long.)
Protective gear: A case ($10) for the SSD will keep the data safe from bumps. A heatsink case ($15) for the Raspberry Pi will keep it from overheating.

An LCD screen 3.5" RPi Display, GPIO connection, XPT2046 Touch Controller ($25): Once it's set up, this screen will show a little bit about the node, including the address it uses to connect to other nodes. This is a key piece that sets RaspiBlitz apart from other Lightning nodes.

My questions
The question is that biitcoin lightning node setup is not hard but is it profitable?
In this kind of setup, to be specific, what can be the profit of someone that setup the node?

You can make use of paper wallet by using bitaddress.org, it is save as long as it is offline, but only one private key is generated by such wallet with a single address. So, you can not use it for making transactions than to just hold coin on the wallet and let it remain offline.

For making transactions and for ease, the best you can do is to by hardware wallet like trezor or ledger nano. Or, if you have a device like a phone that you are not making use of again, you can set up an electrum cold wallet on it, while you will need another phone as watch-only wallet. To do this, you can follow the quote below:


Coinbase.com is not a cold wallet, also not even a wallet that gives users private key. Not recommended in this case, adn it is worth knowing that not your key not your coin on blockchain.

The OP had imported the seed phrase but commented not working. I think this could be more of internet connection failure to synchronize the blockchain. The OP should try to check his internet connection and make sure it is working perfectly.

PoS can be convenient but not better and not the best. PoW is the best in my opinion.

People are working in electricity companies, which means they are employed, the more electricity people use the more gain for the electricity companies and the more likely their workers will increase. Bitcoin is not about the usage of electricity, bitcoin mining makes miners to let electricity companies to generate more electricity as they use it and gain and pay electricity payment which can lead to electricity companies development. But how can the PoS improve the power (electricity) sector? It can not.

Also, how about companies producing miners, PoW helps in the development of companies producing miners and other mining equipments, which PoS is otherwise.

PoS is truly easy to setup but POW brings more development to the community.

Bitcoin mining relies only on electrical energy source, there can be free energy sorcees but these energies have to be converted to electrical which will take processes that will require money. And if it requires no money, it has nothing on bitcoin blockchain as it will be used to still defend it by people that mines, it will only be the best alternatives than wasting money on electricity payments but yet individuals will still have their mining hardwares running at low cost to generate more hash rates that will protect bitcoin blockchain.

You are completely wrong, bitcoin blockchain is the strongest and now obvious in a way it is not vulnerable to 51% attack and the hashes generated is still increasing and making the blockchain stronger.

You have no point to proof and you know nothing about 51% attack. Are you comparing Ethereum 2.0 to bitcoin PoW, bitcoin blockchain is much more and more stronger than ethereum blockchain. Ethereum 2.0 PoS can be good, but it is proof of stupidity if you are comparing it to PoW. Bitcoin blockchain is also the strongest of all.

Bitcoin blockchain remains strongest not because miners pay for electricity, it is because they mine to make profit while it happened in a way attackers already know bitcoin blockchain can not be compromised as the attackers hashes are not significant to what legit miners are generating.

There is no two reasons why Satoshi Nakamoto remain pseudonymous, it makes bitcoin completely to be decentralized. Although, Satoshi is the creator of bitcoin, but who controls it? Nobody. Satoshi disappearance is an indication that bitcoin is owned and controlled by nobody.

This is worth knowing as institutions are shifting gradually from traditional assets into bitcoin. A new survey of global fund managers reveals that Bitcoin has climbed in the rankings of “most crowded trade” beating out traditional investments like gold and bonds. Bitcoin was third on the overall list of options for the category, named as the busiest trade by 15% of survey respondents. Only tech stocks (52%) and short dollar positions (18%) ranked higher.

The Global Fund Manager Survey was conducted by Bank of America Merrill Lynch between the period of Dec. 4  to 10 and asked 217 fund managers collectively responsible for $534 billion in assets, a series of questions related to trends in investor behavior. A related question asked respondents if they held Bitcoin long positions, to which 15% responded affirmatively, which is three times more than last month’s total of 5%.

Asset managers around the globe are losing confidence in the dollar, encouraging them to seek out inflation-resistant investments for their clients.

About Satoshi Nakamoto, it is pseudonymous, just do not bother yourself about the name than being a developer that created bitcoin and that is all.

Bitcoin is now attracting institutional investors, 2020 has gone down as a transformative year for Bitcoin, with firms like Grayscale, PayPal, MicroStrategy and MassMutual rewriting the narrative on digital assets. Now, a United Kingdom-based investment manager has added Bitcoin (BTC) to its portfolio, underscoring the ongoing institutional shift toward digital assets.

Ruffer Investment Company Limited, an investment manager with shares listed on the London Stock Exchange, has disclosed its new Bitcoin strategy. In a performance update and manager comment posted on Tuesday, Ruffer said it has added Bitcoin to its Multi-Strategies Fund, primarily as a defensive move against the “continued devaluation” of fiat money. The fund now holds roughly 2.5% of its assets in Bitcoin.

The allocation was made in November after Ruffer reduced its exposure to gold in favor of BTC. The firm said: “We see this as a small but potent insurance policy against the continuing devaluation of the world's major currencies. Bitcoin diversifies the company's (much larger) investments in gold and inflation-linked bonds, and acts as a hedge to some of the monetary and market risks that we see.”

Did you mean every ranked member on this forum think in the same way by commenting in a way newbies can not understand? Well, if that is the case, you are wrong. I opened my account this year as an inexperienced user, this forum really helped me, especially on how to avoid scam, how to go about wallet and how to have online privacy. Also, I have never seen a forum like this before, ranked members show accuracy in their postings. This forum is free for everyone, just post the way you like but if you want to rank up, you need to take advice, although it can be painful.

You need to see your weakness, there are many new users on this forum that did ranked up and many more will rank up.

This is another failure of centralization of the internet, if the internet is decentralized and the web 3.0 evolves, this kind of thing will not happen as it will be more robustic and powerful just like bitcoin blockchain. That said, if taking bitcoin blockchain as an example, bitcoin blockchain has never been compromised before just because it is acceptable by people as miners protects it, web 3.0 will also be similar and will be protected by people just like in the case of bitcoin blockchain not by centralized body like google and the likes, and will never cease in operation like google just did for 45 minutes yesterday because it will be decentralized

---

According to a tweet from Google, the company suffered an “authentication system outage” that essentially rendered a wide variety of servers useless for about 45 minutes because the system was unable to confirm users were who they said they were. It seemed to largely affect Europe and extended well beyond what people might normally associate with not being able to get into their email. On Android smartphones, for example, native apps like Google Maps ceased to work, and internet-connected devices through Google Home were seemingly also down.



From Gmail and Google Calendar to YouTube and even Google’s two-factor authentication, the outage temporarily ground online work to a halt for many, including publications that would have otherwise been reporting on the outage. “If an internet giant like Google can suffer such a major attack – denying millions of users access to basic internet services – it just goes to show that under the surface of the shiny web interfaces we see, internet infrastructure actually hangs in a delicate and vulnerable balance,” said Jaro Šatkevič, head of product at Mysterium Network, an open-source Web 3.0 project focused on decentralizing the internet.

There is an article created by Ratimov that can help you, or you can start by watching the video on the article which the link is also posted below.

[Tutorial] Crypto taxes for beginners

Video about crypto taxes
https://m.youtube.com/watch?v=NBFCvVBpscA&feature=youtu.be

But you will still need to relate it to the crypto regulations in your country by finding out the percentage gain you are going to pay in taxes.

Just know that deposit will not be taxed, crypto sent to recipient will not be tax. Only the profit you make before withdrawal and after trading will be taxed.

There was a topic I created some days ago about DeFi in which wbtc was even included.

Exploits and flash loans are just the beginning, defi economy Is less private
https://bitcointalk.org/index.php?topic=5292279.msg55658192#msg55658192

I think that enough will not make me make used of DeFi projects as they are less private, although the news emphasized on the ones built on ethereum blockchain.

You are right about wbtc. But just a point to correct my mistake above about the second point, I later deleted it. It is BTCTRON not TRCBTC

There are some DeFi projects that are 1:1 backed by bitcoin, but these coins are DeFi projects like Wrapped BTC and RenBTC. These projects provide means of using these tokens in form of bitcoin to make active income.

You can get some info here:

Your question was not coherently asked which makes it unclear. Can you try to explain clearly what you are asking our help for?

Was the exchange you are using hacked?

If so, what is the name of the exchange?

Did you mean you need to claim back your lost funds?

There is no exchange called wex, but there is an altcoin called wexcoin (wex).

Were you unable to exchange the coin on a exchange platform you are using? Just give clear explanation.

You should not reuse a paper wallet because your coin can be lost, because it is not safe to reuse a paper wallet. Paper wallet is meant for holding. It has one address which makes it totally unfit for reuse not to comment of its complications.

If you want an offline wallet that you can use for making transactions instead, why not try hardware wallet, but using electrum on two devices. One as watch-only wallet and the other as the main cold wallet, the cold wallet will have your private key offline and will be used to sign transactions which you generate on the watch-only electrum wallet.

Never try the idea of reusing paper wallet.

About coinbase that canceled margin trading, it is not the only exchange that supported margin trading, I hope many people would have left for other exchanges that support margin trading.

You are right that the governments are tightning crypto regulation in general but no much pressure on crypto derivatives, I do not think there is much to be worried about, if a certain country governmental policies do not favour, there will be some (most) other countries that will favour. In this case, about crypto derivatives like margin and future contracts, I do not think these can be affected, there will be many exchanges that will always be providing these services. Although, the KYC, AML and CTF regulations for users using most exchanges can become mandatory in accordance to governmental policies, but this should not affect crypto derivatives.
 
We all know what most government are trying to do, but I do not think it is in relation to derivative trading because only few do not support crypto derivatives, but on regulation of how exchanges can know their customers in a way crypto criminals activities will decrease is their main aim, which will not affect crypto derivatives in my opinion.

There are some countries that ban future contracts like USA while UK has being tough on crypto generally, but that does not mean is will affect crypto derivatives as many countries support it, only psuedonymity is what most want to avoid.
