What are your thoughts about this?

It's a big fuss about a feature that's not really special, other companies also have for transferring money between their own customers.
One example that comes into my mind is Revolut, where you can transfer to a phone number (may be considered less private, but it's the same thing).
The catch is that both sender and receiver have to be customers of that company since the transaction is off-chain.
9322  Bitcoin / Bitcoin Technical Support / Re: Bitcoin wallet and addresses on: February 27, 2020, 04:11:40 PM
I have a question about the structure of Bitcoin wallet.
In bitcoin full node client and electrum (SVP) wallet there are multiple bitcoin addresses.

If I use different addresses each time, will I have a total balance on a single wallet. Or each deposit is totally separate?
If I receive multiple deposits to different addresses of total 10 BTC for example, and I want to withdraw the total amount on a different wallet address, will I have to do withdrawal from each address separately?

Each deposit is "separate" even in the same address! They're called inputs.
When you make a transaction, that's built from one or multiple inputs. And if on input has to be "broken" in order to obtain the correct amount, the transaction will also create an output towards an address of yours. That's called "change" (it's the same concept like you have more banknotes, just they are most probably of different sizes)
However, you just type in the recipient, the amount you want to send and maybe the fee too and the wallet will do these operations for you.


And finally how Exchange addresses work? It seems Exchanges have a single wallet, but they create different wallet address for each user? Do they (the exchanges) receive all deposits on a single wallet that can be managed by single administrator? Does exchanges use standard Bitcoin wallets to operate customers accounts or they use some specific software?

Exchanges have one or more deposit addresses for an user (especially if he clicks on "change my address").
The money those addresses receive become numbers in a database.
All the trades are really operations on those numbers in exchange's internal database (for various coins/currencies/users).
When an user withdraws, the amount is subtracted from the internal database and it's sent to the address the user wants to withdraw to. The funds are sent from the exchange's wallet and it may be from any of users' deposit addresses or not, depending on how their software is made.

It's actually more complicated since the cold wallet also may come into equation and also they may consolidate their inputs from time to time (send money to themselves to not have too many inputs; this helps on reducing the tx fees)

Tails page already has step-by-step tutorials for the major operating systems one wants to install from: https://tails.boum.org/install/index.en.html

Probably this won't change the table, but right now Matrixport.com has one open slot.

We're going for Another 2 Weeks!

1 spot OPEN.

Edit: it still writes "open", but the one member was accepted

Just noticed I’ve reached over 2000 Activity, 5 & a half years posting here, it’s been a pleasure sharing the forum with you guys.

Congrats! You also have an impressive number of posts, and since I know that you make quality posts, the other stats are not a surprise.
9327  Alternate cryptocurrencies / Marketplace (Altcoins) / Re: Promotion on Bitcointalk on: February 26, 2020, 07:25:28 PM
One of the most common ways to promote your project is:
1. make an ANN so the people can discuss about it.
2. hire someone to make a set of signatures
3. hire someone to manage for you a signature campaign.

These should help:

9328  Other / Beginners & Help / Re: Don't auto Save your login details on: February 26, 2020, 12:02:57 PM
Firefox has an in built password manager, lockwise.
If you auto save your logins in firefox  this won't happen. But you should never do this is on public computers anyway.

Chrome has its own and it stores them encrypted with different password that the one for user profile.
But this doesn't matter. It was already said (I'll bold it and make it big) and it covers the story correctly:

You should never be logging in to anything using a public computer.
9329  Alternate cryptocurrencies / Altcoin Discussion / Re: Coronavirus ain't helping on: February 26, 2020, 11:56:49 AM
if this isn't contained anytime soon all dreams might be nothing but dreams this year, Coronavirus ain't helping at all

The outbreak has caused a pump. Some traders know how to speculate emotions (fear) and some panicards were buying in. But no, that's not relevant.
On the long term, at least Bitcoin should rise. Maybe in March as some say, maybe after the halving as others say, maybe later. Patience is the key. And yes, this should rise the altcoins too.
The fact you expect miracles this year is not healthy.

I also expect some more price increase this year, but if it won't happen it's also fine.

Containing Covid-19 is difficult. Governments are not as capable as you'd think, people are more careless than you'd imagine and so on.
But Spring is near. From what I've read the temperatures over 25 C should be slowing/killing the virus.
Interesting enough, such temperatures may come when we'll be pretty close to the halving.

Such technique can be used if you want to have your text (or signature!) on that page.
I think that there was a campaign (signature or bounty) which was paying only the posts from the first page of a thread/topic.
But from what I see it's not the case - it's something on the .. 9th page. So it's some sort of spam that doesn't make sense to me.

Try reading the news instead of staring into your own ass all day long.  Wink

Try to stay sober from time to time. Maybe you could get some sleep now, maybe you get a glimpse of reality when you wake up.
9332  Other / Beginners & Help / Re: Where is the electrum exe file on: February 26, 2020, 08:58:59 AM
Make sure you didn't download the portable version

The portable version creates its data folder under the exe folder, not in %AppData%\Roaming\Electrum (where OP data is located).
9333  Bitcoin / Bitcoin Discussion / Re: Bad News for Bitcoiners, The price will not go up at the Halving, but DOWN$! on: February 26, 2020, 08:10:05 AM

You have put quite some effort into all that bullsh*t.
Of course, whoever reads only the title or the things you wrote without using their brain to read a tad more, they deserve their fate.
But for most it's just a wasted effort.

BTW, you sound so sure like you'd know the future, at least the lows. Can you tell us when will the new low happen so we buy only then?
9334  Other / Beginners & Help / Re: Where is the electrum exe file on: February 26, 2020, 07:59:09 AM
Another idea could be that maybe some antivirus contained the installer.
In that case you should look for folders like c:\VTRoot\HarddiskVolume* and what's inside them. There could be a copy of Program Files with everything "installed" there.

As the coronavirus spread in Italy recently, bitcoin market has dropped 3% and also the traditional market including all the top ranked cryptocurrencies. Can coronavirus spreading be the cause?

No. I'll tell you the real reason, but please only put this into newspapers if you mention my name.
It's because Trump was snoring last night.
9336  Bitcoin / Bitcoin Discussion / Re: Found old wallet with 0.5 BTC on: February 25, 2020, 10:27:24 AM
I just want to ask what if I am a ledger owner then my wallet have some crypto but I lost the ledger and I have all the details about the wallet even the passphrase,
Could I access it to a new ledger or is it lost forever?

If you have the seed (probably 24 words) you can access your funds with or without a new Ledger.
With a Ledger it's safer, but an Electrum can already do it.

Eventually all countries will mine top crypto currencies.

I am not convinced why a country would mine crypto, especially Bitcoin.
For a country it can be way more profitable to invest big in some crypto and then play with the market. As a whale it can create quite some waves and profit from them.

A country banned from the international market may mine anonymous coins indeed. But buying the necessary amounts of hardware may not go unnoticed. So I'd stick to the whale idea.

No matter when a new project pops up, if you want to spend money investing in it, you have to do properly your homework, researching the background, the team, the long term viability of the project ...
If you invest without thinking you are not better than gambling.
9339  Bitcoin / Bitcoin Technical Support / Re: Faster sync would be nice (i.e. soooo slow) on: February 25, 2020, 08:19:52 AM
stick in a 1tb ssd load the core.

Actually a small SSD would do.
It's enough to temporarily symlink the chainstate folder to the SSD until the first/big sync is done, then that data can be moved to the HDD too.
And that's only some 4GB now.
9340  Bitcoin / Bitcoin Discussion / Re: Warren buffett strikes again 😂 on: February 24, 2020, 04:01:06 PM
Accordingly, Buffett is lying or has become so senile that he did not remember what happened just a month ago.

There's a high chance he didn't understand what happened (that he has received a Bitcoin wallet and 1BTC+ on it).
And the only chance I see for that Bitcoin to not get lost is if somebody will recover from thrash somewhere that phone and the wallet it contains.
