Żeby tylko wspomnieć o aktualizacjach win10 bądź androida, które powodują wysypywanie systemów lub niedziałanie hardware, a mają status "release".

We have yet another market-based argument for considering some cryptos (especially BTC) as "store of value" assets. But in the case of bigger crisis/war, there is one factor which is important - power supply. If there will be frequent and long blackouts caused by it (in countries/regions where there is a lot of biggest mining farms), then the hashrate of cryptos would go down causing panic.

Is it just us, or really many of them even just by the name itself sound like a scam (not to mention the "coincidence" related to the release date during the 2017 bull run)?

It could if there will be serious power issues in regions of China where most of the big mining farms are located.

Just to give a confirmation of your statement - it can be said we see the same with BTC. On the Pacific Ocean, there is one small state - called Vanuatu. Their traditional currency (and even you can find it on the flag)...is a boar tusk.

For many people, a boar's tusk has a very small value. But some of the locals found it very valuable and instead of breeding boars for food, they started breeding them for tusks and kept feeding them (any analogies between mining and "wasting electricity"?).
The older the boar, the more circles its tusks had been making and the more problematic, costly and time-consuming it was to feed it (halving, rising mining difficulty and effect on the price of BTC).
Finally, the boar tusks became something more just mere store of value - became a local currency, a symbol of wealth with great reputation (now BTC is a store of value thing, right?)

But anyway, it is nothing but a piece of bone, just as BTC is just a piece of code, right?

And we are not even able to say on this moment what influence may have some factors like this coronavirus on mining of cryptos as such.

Mamy wrażenie, że tutaj jednym z dużych czynników może być panika związana z Chinami. Bo jeśli chińskie farmy będą musiały chociaż tymczasowo zawiesić pracę z powodu np. przerw w dostawie prądu dla podmiotów prywatnych - spada hashrate i ceny wielu krypto mogą spaść i to znacząco.

Depending on how this new virus will spread, in case of potential power shortages (what we believe should not take place), we may see a huge changes in Bitcoin price. This could affect as well factories which are producing minign equipment etc.

In cases like that, the most likely solution would be that you may not be able to get your withdrawal accepted unless you can prove that you are the verified/registered owner of a wallet (supposedly from some sort of a white list accepted by authorities as meeting FATF standards).

Correct us if we are wrong, but this would require one-use wallet. Is there any way to create a single-use wallet which is one way only(out)? What if someone would send BTC to such non-existent address (already emptied)?

Technically speaking, we already have a body which tries to do so, known as FATF. And even though their rules do not have binding power, the states which are not following the "recommendations" are facing severe repercussions including partial or full cutting off from the international financial systems.

Well, many people first heard about cryptocurrencies during the last ATH for alts BTC and decided to take loans to buy them close to the peak. Greed blinded them.

Po prostu ta wojenka, który z forków Bitcoina jest prawdziwym BTC spowodowała, że ludzie na każdy nowy projekt mający w nazwie słowo "Bitcoin" reagują BARDZO podejrzliwie. I chyba nic tutaj się nie zmieni, choćby sam Satoshi przemówił.

Even better - you can even trade manually literally 3-4 times per year if you sold/bought close to peak/bottom and make a few hundred percents of ROI within even a couple of months.

Especially if we are speaking about IT sphere - if you do not evolve/adjust/update/improve as the time goes by, it means the project is dead. Do we have things to improve? Of course, now LN is the most important element of the development, as we learnt in Dec 2017, that BTC transaction could take even 24 within its blockchain. Other features can be taken from other cryptos, like ETH (contracts, dapps).

The only feature which would be potentially harmful for BTC would be full privacy (like of privacy coins), as this would automatically cause a hostility from authorities and could lead to bans for BTC (as officials are too afraid of any sort of possibility allowing money laundering).

If we go into this direction then we should realize a few things:
1. There are people imprisoned for stocks pump and dump schemes (illegal there, not forbidden on crypto markets). Why eg. those people would not take an opportunity to shorten their sentence to eg. 10 years by trading cryptos on behalf of secret services? As well - we know that whales (which are often early adopters or parties/companies which know when to dump to buy much cheaper and hoard their BTC/any other crypto) can by a single transaction change the trend/boost it significantly.
2. SS like FBI, unlike normal individuals, can pass all the KYC with fake identity on all the exchanges.
3. Unlike hard cash, for the purpose of black budgets of such services (black budget is an unofficial/illegal one like paying bribes to corrupt foreign officials etc.) - instead of using cash which has its physical size, you can fir $4000000 value in crypto on a small hardware wallet.

Is it a true rumour, that alcohol and temperatures above 57*C are deadly to the new virus?

This is possibly the direction other countries will try to go.

W wypadku LTC w ub. roku pompa zaczęła zchodzić jakiś miesiąc przed halvingiem. i z górki $200 mamy niecałe $60 na chwilę obecną. Więc istnieje prawdopodobieństwo, że będziemy mieli 2 górki w ciągu najbliższych miesięcy.

It applies not only to dealing with cryptocurrencies but any other virtual goods, including such thing like World of Warcraft account. You may face chargeback in each case where you have no paper proof of shipping.
