1  Alternate cryptocurrencies / Altcoin Discussion / chain and protocol on: October 30, 2022, 02:38:21 PM
there is a column "All chains" and "All protocols". The name under them are different. For example in chain, it looks like this are the different blockchains that exist. For example Ethereum, Avalanche. But under "All protocols" for example we can not find "Ethereum".

A) So what is the protocol?

B) Why is it important to chose a protocol on ?

C) Can it be, that different blockchains use the same protocol?
D) Can it be, that different protocols are on the same blockchain?

Would appreciate some answer. Thank you.
2  Alternate cryptocurrencies / Marketplace (Altcoins) / Being LP on uniswap on: October 20, 2022, 12:19:05 PM
It is said, that Liquidity Providers on Uniswap will earn from the swap fees, that the trader have to pay.

Question: Is the amount a LP will earn depending on the pair he is providing liquidity?

For example will I earn more with ETH/USDC than USDT/USDC ?

Or do all become the same amount?

(I think it would not be fair if everyone got the same amount, because "impermanent Loss" is bigger with ETH/USDC than USDT/USDC.)

Thank you.
3  Alternate cryptocurrencies / Marketplace (Altcoins) / staking USDC possible? on: October 17, 2022, 01:55:07 PM

Is it technically possible to stake USDC (from Ethereum) or can we only stake ETH?

Or in general: Can we also stake coin tokens on "Proof of Stake" blockchains or only the basic coin from the chain?

(Pleas note: I am talking about staking, not lending.)

Would appreciate some answer. Thank you.

Edit: correction: stalk -> stake
4  Bitcoin / Bitcoin Technical Support / BTC: cutting the trace on: October 15, 2022, 10:56:28 AM
There are people that use Bitcoin mixer to cover the origin of there Bitcoins with a veil.

I will never make this, because this would make my BTC suspect. And there is a risk to make my BTC's dirty.

But here is my technical question:
When we change our BTC into another crypto and after change them back into BTC, I guess in this case it would no more be possible to trace back the origin of the  origin BTC.
Am I right? Or do I miss anything?
Of course if we make the change on a CEX, it would be possible to trace back the origin, because the CEX will have a history-protocol. But I guess not, when we make this via DEX.

If I am right: Why do people use BTC mixer? Isn't changing BTC into another crypto and change them back, not the much better solution to cut off the trace?

Would appreciate a competent answer. Thank you.
5  Economy / Exchanges / Poloniex withdraw limit real? on: October 14, 2022, 09:53:27 AM

Any experience with poloniex?

It is sead, that we can withdraw coins until 50000$ per day without KCY with tier1.
This is unbelievable.

Or does this mean 50$ (50.000) ?

I am just worried, that when I want to withdraw 2000$, then it is said, "Sorry, we need KCY".

Would appreciate if someone has experience with this. Thank you.
6  Local / Altcoins (Deutsch) / uniswap: 0xbtc 0xmr on: October 14, 2022, 07:23:26 AM

Auf findet man Tokens wie: 0xbtc 0xmr

Was genau bedeutet 0xbtc oder 0xmr?

Und was bedeutet 0x?

Besten Dank.
7  Local / Altcoins (Deutsch) / DEX Uniswap, wie einsteigen? on: October 14, 2022, 07:17:18 AM
Kann ich auf der DEX Uniswap nur mit Handeln beginnen, wenn ich ETH habe?
Muss ich also zuerst BTC in ETH tauschen, bevor ich mit Uniswap zu handeln beginnen kann?
Oder kann ich auch mit Uniswap meine BTC's in ETH umwandeln?

Eine Antwort würde mich freuen. Besten Dank.
8  Alternate cryptocurrencies / Altcoin Discussion / Stablecoin USDT: Contradictions on: October 13, 2022, 08:12:49 PM

On this page:
... there is a table with the title "USDC vs. USDT vs. BUSD: Differences".

In the first line "Blockchain" of this table are mentioned all blockchains of USDT.

So when I understand this page right, USDT is on the following blockchains:
Ethereum, Solana, Tezos, Kusama, Algorand, Avalanche, Tron, Polygon, EOS, Liquid

But further in the text it is a saying:
Quote: "Having different blockchains results in a variety of advantages, such as the speed and utility of transactions. While USDT only runs on a single blockchain, USDC and BUSD have multiple blockchain options, allowing buyers to trade and transfer across them."

So this is a contradiction. First it is said, that USDT is on the blockchains Ethereum, Solana, Tezos, Kusama, Algorand, Avalanche, Tron, Polygon, EOS, Liquid.
But then it is said, that USDT is only on a single blockchain.

Very confusing.

Would appreciate if anybody can explain this.
9  Other / Beginners & Help / change real btc against real Monero on a DEX: Is this (technically) possible? on: October 13, 2022, 03:30:46 PM
There are "coins" that lie on their own blockchain (like ETH, BTC, Monero) and other "coins", that are tokens.

Are there DEX, where it is possible to change "coins" that are not tokens, but have there own blockchain. Or can we only change "coins" with a DEX, that are part of the same blockchain and are tokens?

A) Are there DEX, where I can change BTC against Monero (I mean not tokens, but the real BTC and Monero)?
B) Or can I only do this on CEX?
C) Or are there "copys" of Bitcoin and Monero for example Ethereum, so that I can change Bitcoin tokens and Monero tokens on (for example) Ethereum chain?

Would appreciate some answer. Thank you.
10  Alternate cryptocurrencies / Altcoin Discussion / Stable coin tether USDT: Ethereum vs. Solana vs. BNB Chain, etc on: October 12, 2022, 04:13:59 PM
I know, that a USD stable coin tries to be exactly 1.0000$. However some stable coins can better follow this goal, other less. So it can be, that USDC can lose confidence, but TUSD is still trustworthy.

One of this stable coins is Tether or USDT.
It is said, that ...
quote: "Tether or USDT is available on multiple blockchains such as Ethereum, Solana, BNB Chain, etc."

What does this mean? Are this also different stable coins with the same name?
-Can it theoretically be, that a tether on Ethereum blockchain can have another value than the one on Solana blockchain? And does the arbitrage ensure that these two tethers have the same value?
-Can it theoretically be, that for example the tether on Ethereum blockchain has lost confidence and becomes worthless, whereas the one on Solana blockchain still has more confidence?
-Or is it technically (by design) impossible, that a tether on one blockchain has another value than the one of another blockchain?

Would appreciate an answer. Thank you.

11  Bitcoin / Bitcoin Technical Support / BTC: different address-types, Not all were found in the blockchain explorer on: October 11, 2022, 09:08:15 PM

1. Question:
I have installed a simple bitcoin Wallet on my Android phone.
It generates a bitcoin address for me that looks like this:
bc1qjn...4pt (total 41 characters)

When I type this address into a blockchain manager it does not find this address. Why? What kind of address is this?

But when I type into the same blockchain explorer one of my old address that looks like this:
372YbM...De5 (total 34 characters)
it finds the address.

2. Question:
Can I send BTC from an address like 372YbM...De5 to an address that looks like bc1qjn...4pt ? Or would this lead into problems?

Would appreciate some answers. Thank you.

12  Local / Altcoins (Deutsch) / ETH: MyEtherWallet: Gas on: May 16, 2018, 06:05:36 AM

Ich habe heute versucht meine erste ETH Transaktion auf dem MyEtherWallet durchzuführen, also Geld von meinem MyEtherWallet zu versenden. (Keine Tokens, nur ganz simple ETH.)

Ich verstehe allerdings das Transaktionsgebührensystem nicht.

Beim Bitcoin funktioniert doch das so:
Ich generiere eine Transaktion, und je nach Komplexität hat diese Transaktion dann eine bestimmte Grösse in Byte.
Dann gehe ich im Pool schauen, wieviel satoshis momentan pro Byte bezahlt wird, und gebe diesen Betrag im Wallet benutzerdefiniert ein.
Die totale Gebühr für diese Transaktion berechnet sich dann: Anzahl Byte * Satoshis pro byte = totalpreis

Ich habe natürlich schon etwas über ETH Gas gelesen. Wenn ich das richtig verstanden habe, entspricht das
Gas-Limit bei ETH der Transaktionsgrösse bei Bitcoin und
der Gas Preis bei ETH dem Byte- Preis bei Bitcoin


Ich hätte jetzt erwartet, dass ich im MyEtherWallet den Gas Price eingeben kann und dann die Wallet je nach Tranaktionsgrösse (also Gas-Limit) das totale Gas berechnet.
Aber im MyEtherWallet kann ich  nur das Gas-Limit eingeben. (?) Ich weiss doch gar nicht wie gross die Transaktion sein wird.
Den Gas-Preis kann ich überhaupt nicht eingeben?

Für Hilfe wäre ich dankbar.

13  Local / Altcoins (Deutsch) / Bitcoin Hard Forks on: February 18, 2018, 01:55:12 PM

Ich habe beschlossen, mich etwas mit den Bitcoin Forks auseinanderzusetzen, um herauszufinden, ob es vielleicht ausser Bitcoin Cash und Bitcoin Gold noch andere Forks gibt, die ich "claimen" kann.

So habe ich diese Seite gefunden:
Hier sind viel Bitcoin Forks aufgelistet.

Die folgenden Forks von obiger Seite, habe ich dann auch auf
gefunden. Es sind dies:

-Super Bitcoin
-Lightning Bitcoin
-Bitcoin God (nicht gold)
-Bitcoin Segwit2x “2.0”
-Bitcoin Atom
-Bitcoin Diamond

Auf der Seite
steht dann aber noch weiter:
PAST BITCOIN HARD FORKS: Past hard forks that occurred in or were planned for 2017 include: ... ... ... , and Bitcoin Diamond (futures traded, but blockchain is not live yet). Past hard forks from previous years include Bitcoin XT, Bitcoin Classic, and Bitcoin Unlimited. Yes, that really is a full list of every hard fork before late 2017. Meanwhile, BitcoinRed, BitcoinDark, BitcoinZ, and Bitcoin Scrypt were all past attempts to create alternatives to Bitcoin but were not created as forks.

Da in obigem Zitat noch zusätzlich die alten Forks
-Bitcoin XT
-Bitcoin Classic
-Bitcoin Unlimited
vorkommen, habe ich diese Coins auch noch auf gesucht.

Ich bin davon ausgegangen, dass ich diese Coins ganz sicher bei finden werden, eben deshalb, weil ja oben steht, dass das alles Forks aus der Vergangenheit sind. Also sicher Coind, die inzwischen etabliert sind. Aber diese 3 Forks habe ich bei nicht gefunden.

1. Frage:
Gibt es die inzwischen nicht mehr? Oder hat vergessen, diese aufzulisten?

2. Frage:
Kann ich diese Forks alle "claimen", wenn ich vor dem Fork Bitcoins hatte:
-Super Bitcoin
-Lightning Bitcoin
-Bitcoin God (nicht gold)
-Bitcoin Segwit2x “2.0”
-Bitcoin Atom
-Bitcoin Diamond

Eine Antwort würde mich freuen.

14  Economy / Exchanges / withdraw limit on: February 05, 2018, 08:49:01 AM
Some month ago we were allowed to withdraw crypto currencies of a value of 2000$ a day, if we are not registered with a proof or residence and we did not deposit a passport, ID.

Is this still the same? Can we still withdraw crypto currencies of a value of 2000$ a day in this case?

(I am afraid of the following fictive scenario:
I deposit cryptos in the value of 2000$ on Poloniex. I trade. I have now cryptos of 3000$. I try to withdraw 2000$. Now, Poloniex is freezing my 3000$ and says: "You can withdraw it as soon you give us your ID.)

Thank you.
15  Local / Projektentwicklung / Blockchain: elektronische Identität on: December 10, 2017, 08:28:35 AM
Es gibt jetzt die Blockchain seit mehr als 8 Jahren. Ausserdem gibt es auch seit mehr als 7 Jahren Börsen um die Crypto Coins zu handeln.

Seit mehreren Jahren verlangen diese Börsen von uns, dass wir unsere Identität ausweisen und dafür ein Foto unserer Identitäskarte hochladen. Davor habe ich bis heute grossen Respekt. Was ist, wenn der Server wo die Identitätskarten hinterlegt sind, gehackt wird. Dann könnte es sein, dass Missbrauch mit unseren Identitäten getrieben wird.
Es könnte auch sein, dass ein krimineller Mitarbeiter einer Börse sich an den Identitäten vergreift. Die Identitäten verkauft und dann Unfug mit ihnen getrieben wird.

Ich denke die müssten nicht einmal unbedingt das Foto der Identitätskarte selber verwenden, sondern man könnte auch einfach die Daten aus der Identitätskarte auslesen und dann diese Daten und das Passfoto mit Hilfe des Computers auf eine neue Identitätskarte übertragen. Sozusagen eine neue fake Identitätskarte mit den Daten, die auf dem Foto der hochgeladenen Identitätskarte stehen, erzeugen.

Es gibt inzwischen diverse Anwendungen für die Blcochain. Z.B. "Wetten" oder "Katzen züchten".
Aber stimmt es wirklich, dass es so eine nützliche Anwendung der Blockchain wie "eine elektronische" Identität immer noch nicht gibt?

Wieso nicht?
Einen Markt dafür gäbe es. Ich bin sicher, die Leute würden sich bei den Crypto-Börsen mit einer elektronischen Blockchain- Identität ausweisen wollen, wenn sie denn die Möglichkeit hätten.

Weshalb gibt es das noch nicht? Kennt sich jemand mit dieser Problematik aus?
16  Bitcoin / Electrum / Segwit on: December 09, 2017, 05:04:28 PM
Some time ago Electrum has implemented segwit. Before I try it out I want to ask:

Is it in the meantime secure to send bitcoins to the new segwit addresses with electrum?
Or are there any problems?

Thank you.
17  Bitcoin / Electrum / downgrade from 3.0.0 to 2.9.3 on: November 07, 2017, 08:12:35 AM

I made an update from version 2.9.2 to 3.0.0

As my System is Windows 7, 32 bit, version 3.0.0 was not working.

So my question is: Can I downgrade from version 3.0.0 to 2.9.3 without losing anything. Does this work.
Or must I upgrade to version 2.9.2 because this was the version I had before the update to version 3.0.0?

What do you suggest?

(I did not made a backup before the update to version 3.0.0)
Simply concerned to lose anything.

Thank you.

18  Bitcoin / Bitcoin Technical Support / Hardfork to SegWit2x (Will some people lose all there money?) on: November 07, 2017, 07:57:35 AM

If I have understood correctly, there will be a further hardfork from SegWit to SegWit2x in November.

At the moment a Bitcoin can have three types of addresses:

1. already in power: Bitcoin Addresses like:  1BvayiASVCmGmg4WUJmyRHoNevWWo5snqC (without SegWit)

2. P2SH: Bitcoin Addresses like:   3P14159f73E4gFr7JterCCQh9QjiTjiZrG (SegWit)

3. bech32: Bitcoin Addresses like: bc1q76awjp3nmklgnf0yyu0qncsekktf4e3qj248t4 (Electrum only) (SegWit)

I know: Through a hardfork every person who had Bitcoins before the hardfork will get the "new" Bitcoin with the same public key and the same private key.

Since the hardfork from Bitcoin to Bitcoin Cash I have never transferred my Bitcoins to a P2SH or bech32 address. So my Bitcoins still lie on an old address like (1), see above.

When my Bitcoins lie on an Address like (1), do I then get the new Segwit2x-Bitcoin? Or must I transfer my Bitcoins from an address like (1) to an Address like (2) or (3) before the hardfork starts?

This is a very essential question. Maybe when I do not transfer my Bitcoins to a P2SH or bech32 address before the hardfork, maybe then I do not get the new bitcoin and the old bitcoin loses the whole value. So I now have lost all my money.

Would be very interested. Thank you.


Question 2:
Are the legend Bitcoin Addresses and the P2SH Bitcoin Adresses and the bech32 Bitcoin Adresses all on the same Blockchain?
19  Bitcoin / Electrum / Installing version 3.0.0: Error on: November 05, 2017, 04:25:33 PM

I have just now tried to install version 3.0.0:

My system is Windows 7 32 bit.

My old version was Electrum 2.9.2

I have just double clicked the setup. This was without problems. But when I try to start Electrum now I get the following error:

Here is the German part in English:
Error determining the default activation context for processes. The standard activation context for processes is already defined.

Can anybody help me? What does this mean. Thank you.
20  Bitcoin / Bitcoin Technical Support / Are my Bitcoins clean? on: November 03, 2017, 08:05:07 AM
What are dirty coins?
If anybody who has Bitcoins makes a crime (for example in the dark net) or if somebody has stolen Bitcoins, then this Bitcoins are dirty.

So such a person tries to get rid of them. For example he tries to change them into Fiat or buys Altcoins. If I am the person who gives this person my Altcoins and this person pays me with the dirty Bitcoins I have now this Bitcoins. No I have dirty Bitcoins. (Bitcoins with a dirty source Bitcoin Address)

There can be exchanges who have a black list of such dirty Bitcoins. (Maybe Bittrex?). And if a user who has such Bitcoins transfers them to such an exchange will become suspicious.

How can I check, how clean my Bitcoins are?

I have traded with many Altcoins on Poloniex. Maybe through this I got some dirty Bitcoins?
And I have lended many Bitcoins on Poloniex and Bitfinex. I assume the Bitcoins I lended were not the same which I got back. Maybe through this I got some dirty Bitcoins?

Is there a way to test this for myself?

Thank you.
