Anyone could get a confirmation with 1 sat/byte. But there are a lot of transactions paying 20,30,200, even 400 sat/byte.

However to spend ones bitcoin or convert it back to fiat currency through an exchange it looks like one must enter a private key.

Transacting with this private key without encrypting it would be unsecure... so how does this work? Is this what a digital signature is?

Not sure what you are asking about exactly but what I know, since you use binance, is that they have an internal transfer feature which allows instant and free of charge transactions between its users.
But if you are going to withdraw/deposit to/from an external wallet then you will have to pay fees and wait for your transaction to get confirmed.

I'm not entirely sure what you mean here, perhaps because I do not use any Google products so I'm not aware of what their 2FA options are. If a site such as a crypto exchange says "Scan this code with your Google Authenticator App", then you should be able to use any 2FA app. I have certainly done this in the past and it works fine.

If the service only offers SMS or email verification for 2FA, then you obviously can't use an app - you can only use what the site offers. Both of these are not great choices, but you can make it slightly better by using a different email address with a different password to the one you use to log in to the account, or by using a burner phone with a number you do not use for anything else and which you never use to access the services in question.

Most of these are not open source and do not allow proper encrypted back ups. Google Authenticator in particular is awful from the regard. FreeOTP is no longer in development. Here are the apps you should be using:
Android - Aegis or AndOTP
iOS - Tofu or Authenticator

Even if no DeFi token is built on bitcoin blockchain, it is obvious that bitcoin will still have the strongest blockchain, and it will be the strongest cryptocurrency.

If DeFi projects are basically built on bitcoin blockchian, will the bitcoin tokens still be regarded as altcoins? In my opinion, although they will be called bitcoin tokens and they will be bitcoin DeFI projects but such tokens will still be regarded as altcoins.

Even the various phone and laptop programmers have programmed these devices on default to allow downloads and installation from only safe sources such as Google play store

I came up with my own definition or illustration of merit.

I'm hoping that this system will increase post quality by:
 - Forcing people to post high-quality stuff in order to rank up. If you just post garbage, you will never get even 1 merit point, and you will therefore never be able to put links in your signature, etc.
 - Highlighting good posts with the "Merited by" line.

While we will not be directly moderating this, I encourage people to give merit to posts that are objectively high-quality, not just posts that you agree with.

So, I linked merit to social media likes (just as you like a photo or video on facebook) though not exactly but then, you only or mostly like only photos or videos that are interesting or catchy to you. That's how merits work as far as I understand it for now. It is only given not to you but to your deserving posts or comments. It's a way to say I like this for me and it's good.

I created this thread because I was almost hacked using Punycode attack, thanks to Metamsk and password manager I was able to spot this on time but to be honest, I already started to write a password manually (few first ciphers) when I stopped because something filled wrong about this login.

I was logged in earlier and normally my password and username are automatically filled when I am on the correct website and here it wasn't, despite I was logged in a few minutes earlier and only closed the tab. Additionally on the correct website, when I start to type email or password the login details came up automatically thanks to the password manager, and here it wasn't. Second-time Metamask warned me that I am on a phishing website and didn't let me proceed further.

By the way, what is merit and why do i need that? Seems like everyone is looking for that?
Is that some forum currency?

Once you have it, you get the choice:

Actually, yes you can. A lot of complicated ways to strip the code but you can even just store this page offline if you want: https://wallet.bitamp.com/#/create.html

It'll still generate a new seed for you every time you click, without being connected to the internet. This is all client side, you never transmit it across the internet;)

imagining a connection between bitcoin and some arbitrary thing is not a new thing. for years different people have found different things they try to connect to bitcoin so that they can speculate a bout its price after everything else fails.
i guess it is partly because of the volatility of bitcoin price that makes speculation hard and partly because bitcoin market is unique and has never been following anything else so they try to "create" the correlation for themselves to justify moves that looks odd to them.

What happen with Manchester United right now, why Ole keep stay as Manchester United manager? I think he was failed with Manchester United~

It is a too bad performance. From 6 matches, they only win 2 times, get draw 1 time, and 3 losses. I agree that Man. United need a new coach, Ole can't motivate the players to improve their performances. Instead, Ole sometimes chooses the wrong players as the starters and bad strategy to play.

I am optimistic that Man. United managemet has considered firing Ole if no improvements in the near future. 

PSA: Bitamp wallet means only you have private key access but if your browser is infected with malware allowing hackers to listen in and steal your data, or you somehow lose your private keys to theft, then whoever has it can access your wallet. So keep your private keys safe. Keep your devices clean.

It's not congested, I mean my eth transactions went normally and smooth. I guess you have to contact your own wallet's support if you are the receiver. If the transaction said it's success, the receiver wallet may be the problem . The way I see it, Small gwei took slower transactions but as it was already success in a blockchain, you just have to further wait a little bit more and you'll gonna receive it soon.

Nobody mention that this fee will be minimal at the moment because when you send a transaction to yourself, you need to use a minimal gas limit which is only 25000 gwei.

Stucked transactions occur almost always on very heavily used contracts where gas limits have to be set up much higher also. When we are interacting with very complicated contract or the transaction has to be routed between a few contracts, for example: ETH - wETH - GOLD - wallet, then it makes the gas limit go higher. This is the simplest way to exchange on Uniswap, which needs at least 150.000 gwei gas limit because less will be not successful.

Suggestion: I am using 1inch exchange. You can use their CHI token to lower significantly the ETH gas fees  .
                  This is a DEX aggregator, so you have all Dex exchanges in one place.

Another solution is new DEX nobody talks about called Honeyswap.org


https://honeyswap.org/#/swap

Uniswap clone made on XDAI which makes transactions cost 0.0003$ and there is no network congestion problem, additionally, this is also DEX aggregator.

I think we are seeing a big Uniswap competitor here  .
