No, not possible in the contract itself, it has no relation to any monetary amount of the coin. There are ways to ensure that the token wont be traded below a certain price, some of them like backing the price with other funds were already mentioned.

I dont know the purpose of the token but if its used internally in an application you could launch your own marketplace like ANN did. Any fiat transaction within ANN buys ANN tokens on an internal marketplace for a fixed price. People can offer their ANN in this marketplace but never sell them directly.

Danke Lafu! Bestätigt aber meinen Verdacht, dass die Wallets erstmal eingefroren sind und man nun Gläubiger ist wenn ich das richtig rauslese?

As an XRP-investor you have to keep in mind that Ripples main market is the banking sector, if they fail to convince financial institutes to use XRP, Ripple as a company fails, too. There is a strong competition in this market, on the one hand XLM with the backing of IBM (which still offers the hardware 90% of all banks use) and on the other hand the JPM-coin released last year. The latter gets already adopted by big banks as an easy way to tranfser money in no time due to the fact its not available to the masses and therefore the price is stable. A bank will never use any currency which may lose its value in the blink of an eye

I second this. As an European I would nowadays never use an exchange based outside the EU again. You dont know what comes around the corner with all those regulations, SEC investigations and so on especially in the US. The EU offers some of the best exchanges in my opinion, including Bitstamp, Kraken and Bitpanda. Also bitcoin.de allows trading for EU citizens outside Germany.

What is kind of suspicious to me is that there were lots of good news and rumours last year, too, but no news had any positive impact on the price. Nowadays, a simple rumour is enough to push BTC that hard?
News like JPM releases their own coin, big players entering the market and ETFs were planned are way more positive and should have had an higher impact than "ebay might accept CC" ...

Ich hab zwar keine Coins bei Cryptopia liegen, interessiert mich jetzt aber trotzdem:

Cryptopia hat laut deren Tweet einen Insolvenzverwalter eingeschaltet. Wem gehören denn die Wallets auf der Börse rechtlich? Nachdem Cryptopia ja über die private keys dafür verfügt vermutlich ihnen, oder? Würde das dann heißen, dass dort gelagerte Coins in einem Insolvenzverfahren mit in die Insolvenzmasse mit aufgehen und jemand, der Coins dort lagernd hatte quasi "nur mehr" ein Gläubiger ist?

Well, due to the fact their case is now managed by a liquidator it may now take a very long time to get access to those wallets, if they are ever unfrozen again. I am not sure who is the legit owner of wallets on an exchange, if its cryptopia they may use those wallets to cover their depts.

The interesting part is that they make use of a liquidator. I think this is a very bad sign for people who have their coins in cryptopia wallets. You wont be able to access this wallets anymore, cause they belong to cryptopia and may be used to cover funds from banks etc.

Of course its possible, you can literally do what you want if you are the owner of the contract. Its common among ICOs nowadays to prevent immediate crashes of the token price once the token gets listed and bounty hunters sell their coins for a few bucks.

Could you please explain how someone else was able to take over your account? Phishing for example?
It will definitly help others avoiding the mistake you made!

Well, investing 5 minutes to turn up google and search takes too much time for the average poster, they rather spend those 5 minutes for another meaningless and useless post.

Its a very good sign that some alts are on a frenzy again, XRPs massive gain may be due to the simple fact that it is the cheapest top 3 coin which attracts new investors. It simply feels better to spend 100 dollars on 300 XRP than on 0.015 BTC

They offered it recently, but not only sports. You can eg. bet who sits on the iron throne at the end of Game of Thrones season 8. Didnt bet on any event by myself, but definitly looks fun to bet on such events

The pattern keeps the same: create a currency, mine billions of tokens in your own pocket, hype it so others buy into, sell your tokens and watch the project slowly dying. Repeat with another coin. Want it TRON were a large part of their WP was just copied from other coins?

Mir persöblich wär ja ehrlich gesagt ein wesentlich sanfterer Anstieg fast lieber, die 1k Sprünge in 24 Stunden haben dann doch wieder irgendwie einen fahlen Beigeschmack.
Rein das Umshiften von Tether in BTC kanns ja nicht sein, es fehlen aber irgendwie die fundamentalen News, die Max Mustermann und co dazu bewegen würden, wieder BTC zu kaufen.

Hi Thorsten, willkommen im Forum!

Ich habe damals meine ersten Coins über Bitcoin.de gekauft, da mir vor allem wichtig war, mit einem deutschsprachigen Support kommunizieren zu können falls es Probleme gibt. Würde ich auch heute als Anfänger noch so machen. Bitcoin.de bietet halt nur sehr wenige Altcoins zum Kauf an.

Ich kaufe mittlerweile nur mehr über Bitpanda nach. Österreichische Firma, kenne Mitarbeiter dort persönlich. Deren App ist sehr gut und wahnsinnig einfach zu verwenden, auch gibt es unzählige Möglichkeiten Geld zu transferieren (bis hin zu Gutscheinen die man hier in Läden kaufen kann). Du hast hier direkt auf der Startseite eine Schritt-für-Schritt Anleitung: https://www.bitpanda.com/de

I believe that the altcoin frenzy in 2017 was due to massivly manipulated markets. Look eg at IOTA or XRP, they at least tenfolded their value in no matter of time, XRP eg in about two weeks late 2017.
That is nothing what happens because a handful of newbie investors put 1k or 10k into the market, you need billions to move a coin like this.

I am sorry to say that but there is nothing special about this coin, I cant even find a proper roadmap what they are going to do. The market is in a self healing phase, only projects with a real world usecase, strong team and a vision will survive. All other coins may vanish over the next few years.

It depends on what altcoins we are talking about. People tend to invest in minor projects hoping for "the next bitcoin", which wobt happen again. 99% of all alts are useless with either no real purpose or no working product. Those coins will definitly vanish in the next bull run because money flows into BTC directly.

mjglqw and DdmrDdmr already mentioned why its a very bad idea to open an exchange with your current state of knowledge and skills. I just wanted to add another thing:
Imagine you downloaded the code for your exchange somewhere or had someone write it for you for a few bucks. You launch your exchange and its a bummer, hundreds of people store their coins on your exchange and use it to trade. Imagine further, that the code you use may have a backdoor, the writer of this code may use the backdoor anytime, wiping your wallets and leaving you with hundreds of mad customers, you are bankcrupt in no matter of time.

Dealing with other peoples money is nothing you can do for a laugh, you always have to be 100% sure what you are doing and you need excellent staff to do so.

Umso mehr ich mich mit TA beschäftig(te) umso eher glaube ich das auch, ja. Quasi eine self-fullfilling prophecy: Bots wurden dahingehend programmiert, auf solche Indikatoren zu horchen. Indikator tritt ein -> Bots verkaufen/kaufen -> Indikator gilt als bestätigt.

Gerade rein technische Indikatoren wie eben die Fibonacci-Retracements oder auch die Elliot Waves, welche ja auch auf den FR basieren, eignen sich wunderbar für Bots, da diese mit harten Zahlen wesentlich besser umgehen können als der Mensch.
