Not actually quantum resistance of cryptography, but rather the fact, that quantum computer (we have spoken with IBM employees responsible for quantum computers and they confirmed that) have enormous potential for big data processing and forecasting effects of something over a time (they mentioned explicitly climate change, weather or effects of experiments to save costs) - therefore quantum computer-based bots in the next 20 years can potentially be very effective trading tools.
On the beginning, of course, available just to the biggest players due to the fact, that quantum computers to operate require very specific conditions and adaptations of whole buildings so far.

As well one should consider one important thing - some cryptocurrencies had been invented as a mere tool, not a speculative investment. Therefore you might buy some very promising crypto at $100 level, but it would turn out it is doing fine with its blockchain and meeting its goals when its price is relatively stable at $30s.

Of course, if we are speaking about risk and profit ratio - pump and dump schemes are a good example of that. Depending on the moment you enter such scheme, you may make a few hundred percents of the investment, or spend money for a worthless token. Btw. P&D is banned on stocks for a long time by now, but not on cryptocurrencies.

This was a good example of how mass-media can fuel the hype and actively participate in the creation of a bubble leading to terrible losses and harming crypto environment.

In TV, many non-crypto oriented websites we kept constant inflow of how great bitcoin is, greatest investment in history...and as such unfortunately it made thousands of people looking for easy and cheap investment to put their savings in BTC close to the peak of the bubble. People who knew nothing about blockchain and never heard about BTC before.
Hell, even taxi drivers at 3 AM were so overenthusiastic about BTC.

This is why ATH of 2017 was beyond reasonable expectations.

And in our eyes, this 2017 run resulted in strengthening the whales - who literally could make a fortune, and then slowly in 2018 and beginning of 2019 could hoard their portfolios - and the panic and crypto winter made this job easy.

Just to remind, PayPal is not crypto-friendly (unless you sell a hardware wallet with cryptocurrency on it and have a proof of shipping it).
It is not friendly towards any sort of digital goods in general (there had been many cases that someone sold eg. World of Warcraft very valuable account via PayPal, and soon lost a chargeback case against the buyer who then got back both money and had ownership of account).

EU had proven, that in some cases resigning from own currency could have been harmful in case of crisis. Spain or Greece suffer damages from the last (a decade ago!) financial crisis, and as they could not manipulate its own currency and are unwilling to make really hard reforms.
Yet as long as Bretton Woods agreement is still in force, it is hard to believe that going back to the gold standard or switching to BTC as the worlds currency (instead of USD) will happen in the next several decades.

Some of this issues can be potentially addressed by quantum computers. Of course not in the next 4-5 years but in more or less foreseeable future.

What about quantum computers in the prediction of the market events? There are rumours that the biggest banks already are creating departments dedicated to analyzing and predicting the market.

Teoretycznie sens ich istnienia zdaje się być stosunkowo prosty - by powrócić do "rdzeniowej" funkcjonalności kryptowalut. Czyli szybkiej i taniej formy płatności, a nie przede wszystkim narzędzia spekulacyjnego...


...jakim "cyfrowe złoto" czyli BTC chcąc nie chcąc zostało ze swoją reputacją. Oczywiście tutaj też możemy dyskutować, czy naprawdę konieczne jest istnienie co najmniej kilkudziesięciu kryptowalut które robią dokładnie to samo (lepiej lub gorzej) i niewiele więcej mogą zaoferować. Dlatego myśmy świadomie podjęli decyzję, że na stronach naszego kantoru będziemy mieli max. 2 najbardziej popularne kryptowaluty, ktore wraz ze swoimi blockchainami należą do każdej najbardziej użytecznej kategorii.

I jak słusznie zauważyłeś @Tytanowy Janusz w poprzednim poście, Bitcoin (w przeciwieństwie do mniejszych i nowszych projektów) przechodzi dzięki ogromowi sieci Bitcoina i konieczności uzyskiwania zgodny większości powolną ewolucję, ale nie rewolucję.

Otóż nie do końca:
1. Transfery w stylu XRP są o ile nam wiadomo związane dosyć mocno z centralizacją (co stoi w przeciwieństwie do założeń większości kryptowalut, od właśnie Bitcoina począwszy)
2. Anonimowość - gdyby wprowadzono tryby anonimowe jak w XMR czy ZEC, to akurat obecnie prędzej spowodowałoby to spadek do $1000 niż rajd do $1000000. Z bardzo prostego powodu - władze na całym świecie bardzo wrogo na nie patrzą: w Japonii nie uzyskasz licencji jako giełda, o ile masz je na liście, w wielu krajach jest ciśnienie, aby usuwać je z list kryptowalut (na przykład wymagając form weryfikacji tak czaso i kosztochłonnych, że nie jest opłacalna ich sprzedaż). Co więcej - wytyczne FATF już teraz dążą do wycofania privacy coins w ogóle z wymiany fiat/crypto i crypto/fiat. O ile (a wszystko na to wskazuje) będą dążyć do uniemożliwienia także wymian privacy coins/inne krypto w najbliższych kilku latach, taka funkcjonalność w BTC będzie raczej pocałunkiem śmierci, niż wartością dodaną.

Hence the golden rule of investing "do not risk the money you cannot afford to lose". Anyway - beside pre-paid cards, most of the cards are (especially in the Western hemisphere) often referred in general as credit cards.

My mamy wrażenie, że część środowiska nie jest w stanie pojąć, iż dokonał się postęp i mamy kryptowaluty, które powstały by zapewniać określony zakres funkcjonalności i są jako takie po prostu lepsze w swojej specjalizacji (z szybszymi i tańszymi transakcjami, anonimowością, smart contractami itp.). Szczególnie, że w świadomości ogólnej Bitcoin jest postrzegany obecnie przede wszystkim jako forma inwestycji.

Anyway, the idea of wallet ID with identifiable owner of it is precisely what authorities are looking forward.

As speaking of their functionality - yes, it is needed, their potential is incredible.

Still, it is rather clear that as time goes by and global regulation standards will be introduced - privacy coins would be forced to move to the shadow. Already in Japan, no exchange can get a license if it has any privacy coin listed. Even in the UK, some exchanges are already delisting them or are forced to apply a much wider scope of verification of people buying them.

That's right. Imagine that you will have a superb idea for crypto and use of its blockchain (totally not a scam) - but the new legislation will not allow you to come to the public with it unless you meet requirements which simply cannot be met by a group of developers not backed by a multi-million companies. Many projects with a huge potential would not come to existence, or some of their solutions will not come from what users really need - but what corporation accountants dictate. This could ruin the industry.

We already see that in the gaming industries. Smaller studios known for some genres and legendary titles are purchased by the big corporations and after couple of years these titles and genres are abandoned as not giving as much revenue as expected (even if they generate profits!).

This is true, the BTC hype is pulling whole environment up as speaking of price.

Unless the USA is the biggest economy and its currency has the status of an international one, there is a very little chance for BTC to replace it. As well, the fiat currencies are way more often used for money laundering and illegal activities. Especially in a physical form.

As well, if it not controlled, country cannot manipulate its own economy in such easy way as simply printing more fiat currency out of thin air, but would need to make serious and unpopular decisions instead. This is why until now, some countries of the Eurozone - like Spain and Greece are not fully recovered from the last economic crisis.

In general, BTC transactions can be tracked, and with current FATF guidelines and direction of new legislation - the general goal is that like with wire bank transfers both sending and receiving party will be fully identifiable.

It was not yet really tested as one. Remember, that it came into being after the last economic crisis. Although no one really wants an economic crisis, but without one we are not able to check that.

Theoretically, if the real Satoshi would be back and sold all BTC he owns in a short period of time (let's say 24h), we could see a true bloodbath and incredible panic on the market. Even a short drop below $1000 would not be impossible.
Well, it would not even need to be a real Satoshi, but someone gaining control over these Bitcoins...

Of course you can! The more transactions on a single wallet, the easier it is to track scammer. Already many of silk road users participating in illegal activities are facing charges or already had been imprisoned. And yes, KYC/AMLP/FATF norms require verification for withdrawals, and already there had been cases where scammers wallets on some big exchanges had been suspended, as the stolen crypto was traced there.

As well, this is one of the reasons why officials in many countries are gradually starting to fight privacy coins.

Z regulacjami jest trochę strach, bo tworzący prawo nie rozumieją blockchain jako takiego - obecne regulacje to jest w zasadzie kalka prawa dotyczącego banków i kantorów fiat bez zrozumienia zasad rządzących blockchain. Które to regulacje (jak np. weryfikacja po szeregu dokumentów) zwiększają koszty i powodują opóźnienia w dokonywaniu transakcji.

Istnieje zatem ryzyko, że już wkrótce aby móc przekroczyć roczny obrót kryptowalut powyżej np. 100 000 pln, będziesz zobligowany do ukończenia kursów dla maklerów (z licencją brokerską) lub przedstawić rachunki potwierdzające, że kryptowaluty były użyte do zapłaty za coś - bo ktoś mądry w Brukseli tak wkrótce stwierdzi.
