Professionally, the last few months were very exhausting for me.  But now I am finally on vacation. I have long dreamed of writing my first own book and have now decided to start. Of course, I already have an idea. But just writing away didn't work out well for me. I admire every author who just sits down, maybe drinks a glass of wine and writes. But for me, without planning, only nonsense comes out.

I'd be interested in your experiences. Have any of you written a book? What strategies worked for you to successfully write and publish your book?

If I could choose, I would choose money. I could certainly get money through power, but it would be difficult to get rid of power.

It is not particularly important to me to be able to exert influence on other people or world events. I want my family, my friends and I to live a good life in peace. Money could already lead to some improvements, I think.

Of course, there are no cryptocurrencies that do not consume energy. But there are blockchains that consume more energy. And others that are more energy efficient. Everyone has to research the different advantages and disadvantages for themselves and then draw their own conclusions.

No one has to buy cryptocurrencies. And the buying decisions change the prices and the supply. I'm optimistic that demand will take care of that in the long run. And cryptocurrencies, which I believe can be the next big thing because they have the potential to be a gamechanger, also have a strong community that continues to develop and improve the project. As a result, there are also no perfect cryptocurrencies. But there are those that are constantly improving. And more is simply not possible.

Thank you for all the opinions and views that have been gathered here!

I think it's already likely that Elon Musk will become significantly richer than he is now. And Tesla is a well-known, innovative brand. But even though I believe that electric cars will continue to gain in popularity in the coming years, I don't think that only Tesla will benefit from this. The competition has not been asleep and there are now other car brands that can make good electric cars.

I don't think it's that easy to say what exactly investors should put their money into. The world has been and is currently being shaken by a number of crises. And crises often lead to change. I don't know what the situation is with energy prices in the countries where you live. But in our country, the prices for heating and electricity are rising very sharply at the moment. This is forcing a lot of people to save energy, whether they want to or not. That probably won't affect miners in China or Russia much. But I don't think it's fair if not everyone has the same opportunities to participate.

This is exactly what I see as the problem with Proof of Work Blockchains. Individual miners, especially if they live in countries with expensive energy prices, are disadvantaged. Personally, I think that wealth and power should be distributed more fairly than is currently the case globally.

I also have a broad portfolio and look forward to what the future holds. However, like you, I would be happy to see previously undervalued cryptocurrencies, whose potential I believe in, increase in value and importance!

I also invested quite a bit in Cardano last year and hold my coins. I don't believe in selling out of panic. But I personally only invest money in cryptocurrencies that I don't need immediately. So I can wait reasonably calmly to see how the prices develop. And I am also confident that they will recover sooner or later.

I also find this idea of high energy consumption frightening. But I can understand when other people come to different conclusions. Ultimately, everyone has to make the investment decisions that they think are right and promising.

You can use Bitcoin, but for me it's not the right time yet.  At some point, the price will probably stabilize. And when it does, I will think about using Bitcoin. Until then, I'll hold.

I'm not saying it's a big effort. But it is an effort. But I think it's worth it to be a part of the community and to be able to mine. You don't have to participate in the validations to be able to buy IDNA. Apart from the validations, I think that the groups on Telegram and so on also contribute to a good sense of community.

There is a lot going on in the crypto market at the moment. Let's see what will change in the future. I think that maybe some of the more popular cryptocurrencies will crash, while some previously undervalued cryptocurrencies will probably get the chance to develop their potential. And I think, as I said, like you, that green and energy-efficient cryptocurrencies that maybe even enable sharding will have advantages.

Who wouldn't want to become rich? If you have little or no idea about cryptocurrencies, I would set more modest goals first. For example, to invest the money in such a way that at least the loss in value is compensated. In order to have great opportunities, you have to take bigger risks more often. If you are completely new, however, I would first and foremost make sure not to invest too much money.

I would also like the virtual world to be fairer than real life. But I think some developments are pretty similar. Unlike conventional currencies, cryptocurrencies wanted or still want to be decentralized. The power should not be in the hands of a few. Nevertheless, it is now the case, especially with popular cryptocurrencies like Bitcoin, that large, organized mining pools have much more influence and benefits than individuals. This is not entirely different from the general distribution of wealth and power.

The fact that every vote in the community counts equally is something I think is better with cryptocurrencies like Idena, which are based on proof of personhood. But that requires a crypto identity that really ensures that each account can only belong to a single, real person. Getting such a crypto identity takes some effort. But in return, every participant has the same chances to receive rewards and to have a say in the game.

What are the requirements and regulations for cryptocurrencies is already not the same everywhere in the world. And I don't believe that there will be a globally uniform solution in the future. The EU Parliament recently discussed a ban on proof of work, but then decided against it. This time. But I wouldn't want to rule out the possibility that in the future there could be specifications for the power consumption of cryptocurrencies in the EU, for example.

I also believe that there is no evidence of how high the percentage of cryptos in climate change is. The global climate is incredibly complex and has so many variables that it is impossible to say exactly what is having what effect now. But there's no question that the climate is changing, is there? And also that the effects of climate change will not be particularly pretty. That's enough for me to try to live more sustainably. But it's okay for me if other people see it differently.

I believe Proof of Personhood is attractive not only because of its energy efficiency, but also because each participant's vote counts equally. So you don't have to be a member of a mining pool or hold a large share of coins to participate profitably.

The last movie I saw was "The Batman." It was okay, but I liked "The Dark Knight trilogy" better.

It's not quite that simple, I think. Energy is a limited resource and energy consumption is likely to play a role for some time to come. Of course, solar energy can be used for PoW. But at the moment we have the situation worldwide that there is not enough green energy yet. So if green energy is used for PoW, this energy is missing elsewhere. This will probably not be the case forever. But at the moment I see that as a problem.

The thing is, I think PoS is a better solution than PoW in many ways right now. But I see it like you do. PoS is not perfect either and has a few disadvantages.

Yes, that's one of the problems I see with PoS. Early investors or wealthy investors who hold a large portion of the coins can, in the worst case, decide about the network and exclude participants or transactions. Also, the consensus rules could be changed by such investors, right?

I do not have the human status yet. I only came across Idena at the beginning of the year when I started to get more involved with energy efficient cryptocurrencies. At first, I just read a bit about it until I started participating in the validations. Unfortunately, it didn't work out for me for a week because I had an important appointment at the time. But if you can't be there occasionally, it doesn't really matter.

I don't think PoP is 100% perfect yet. But the community is developing the project together. And each participant has only one vote, which counts the same for everyone.

I also think that the development will go in this direction. Sometimes the path will lead to dead ends or will have to be optimized, but I also think that the development will generally go in the direction of sustainability.

Yes, that's exactly my plan and that' s why I asked my question at this place in the board.

Globally, of course, energy consumption by Bitcoin does not account for very much. However, Bitcoin probably consumes as much electricity per year as a quarter of Germany's electricity consumption. I think that's not a small amount.

I think it's good that there is an increasing focus on renewable energies. However, there is not enough renewable energy for the whole world. What is used for Bitcoin is then lacking in another place, isn't it?

I think that at the moment it is important to save as much energy as possible. But I can understand if other people have different views.

And in the EU, a ban on POW cryptocurrencies seems to be on the agenda.... Even though I don't think that will be realized.

What would you say are the benefits of POS?

Thank you, I will do it that way. I believe that over time people will move towards more sustainability. The only question is how long that will take.

So far, I have only had my own experience with Idena. But there are also other cryptocurrencies that are based on Proof of Personhood. If you are wondering about the energy consumption, just read about the similarities and differences between POW, POS and POP.

Yes, I know. But the process also seems to be delayed. Perhaps it is more difficult than expected?

I am watching with concerns the development of climate change and global warming. While I believe that cryptocurrencies make only a small contribution, even many small things add up to a large number.

Bitcoin consumes a lot of power and I don't know if that can change. What do you guys think? As far as I understand, the trust in Bitcoin is mainly due to the proof of work mechanism. And with this, the high power consumption is probably inseparable?

I'm considering investing more in altcoins based on proof of stake or proof of personhood. What do you think are the advantages and disadvantages?

Bei einer legalen Möglichkeit Cannabis besitzen zu können, würde ich mal vermuten, dass auch Eigenanbau zumindest in einem gewissen Umfang erlaubt sein wird? Wobei dann halt vielleicht wieder der Punkt kommt, dass das die staatlichen Einnahmen schmälern würde, wenn die Leute nicht kaufen, sondern selbst anbauen.

Keine Ahnung, wie die Preise in Deutschland sind. Aber in Österreich kann man legal Samen und Stecklinge kaufen (sofern man sie nicht zur Blüte bringt, sondern davor umschneidet, eh klar!) und die kosten definitiv keine Unsummen.

Schwankende Kurse kennt man ja auch aus dem Kryptobereich zur Genüge. Und natürlich sollte man nur Geld investieren, das man nicht zum Decken der laufenden Kosten benötigt. Ich denke, das ist jedem halbwegs vernünftigen Menschen klar. Freut mich übrigens für dich, dass du durch Diversifikation in Summe mit einem Plus aus dem letzten Jahr gekommen bist. Auch wenn immer noch Luft nach oben ist, zeigt es ja doch, dass man viel richtig gemacht hat. Mal schauen, welche Chancen dieses Jahr bringen wird. Tun wird sich sicher noch viel, egal ob Börsengänge oder Kryptokurse. Man darf gespannt sein! 

Je nachdem in welche Kryptowährungen man investiert, ist man schon auch im Bereich des Spekulierens, würde ich sagen. Ein klein wenig Erfahrungen mit sowas habe ich schon, aber zum Geld anlegen habe ich bislang auf nichts hochspekulatives gesetzt. Bei IPOs wird es wahrscheinlich auch von bis gehen, oder? Wobei man natürlich auch da nie eine Garantie bekommen wird, wie es beim Börsengang genau laufen wird. Sowas ist ja immer auch ein Stückchen weit für Überraschungen gut.

Ich war davon auch betroffen, hatte einen kleinen Teil vorübergehend dort geparkt. Jetzt halt dann woanders. Ist ja jetzt nicht so, als hätten sich Festgeldkonto und Bank in Luft aufgelöst. Sie haben sich von der Kundenbeziehung mit mir getrennt? So what? Gehe ich mit dem Teil meiner Rücklagen halt eine neue Beziehung ein.

Naja, naja. Ob man bei ICOs nichts in der Hand hat, ist natürlich immer auch eine Frage der Definition. Coins kann man jetzt nicht angreifen, ist wahr. Aber das trifft auf das Geld auf deinem Girokonto zum Beispiel auch zu. Und es gibt durchaus auch ICOs, bei denen man Eigentumsteile erwirbt, also nicht gänzlich unähnlich wie bei Aktien.

Warum keine Start-Ups? Ich kann mir schon vorstellen, dass das risikobehafteter ist. Aber wenn man breit streut, kann man etwaige Verluste ja auch abpuffern. Nachhaltiges Investieren interessiert mich schon und ich denke, dass es da einiges an Zukunftspotential gibt. Ich mache mich da mal weiter über Unternehmen vor dem Börsengang schlau. Im Netz finde ich aber nur recht kurze Listen mit geplanten Börsengängen. Wirkt auf mich nicht vollständig. Aber wahrscheinlich ist da auch viel Insiderwissen?

... und in Österreich hat Gesundheitsminister Mückstein den Tennisprofi Dominic Thiem zur Impfung aufgefordert. Obwohl dieser, soweit ich das mitbekommen habe, nicht mal komplett dagegen ist, sondern laut seiner Aussage auf einen Totimpfstoff wartet. SPÖ-Chefin Rendi-Wagner hat sich dadurch veranlasst gesehen Thiem öffentlich zu einem Impfgespräch einzuladen.

Ich finde es auch kurios, welche Ausmaße das annimmt. Hätte ich Anfang 2020 so nicht zu träumen gewagt.
