so how do we know that crypto exchngers dont sell us the coins what they dont exisit?

and how do we know those big funds who bought or pretinding to buy or sell some big ammounts of cryptocurrency `?
how do we know they dont lie us ?

Tether is an interesting situation. It may be more complex than that. For example, if the US government were to seize Tether's bank accounts, the value of USDT would drop as USDT holders flee to other currencies. However, similar to April 2017 when Bitfinex and Tether lost banking capabilities, this could catalyze a bullish move in the overall crypto market as USDT pairs drag the rest of the market upwards.

In my opinion, this has nothing to do with decentralization. The main aspect of crypto is that my spendings are untraceable. With this card VISA always can provide data to someone, and why do I have to submit all my Personal data for this I already did it for my bank, and exchange which transfers money from bank to exchange and vice versa. I would rather wait that 6 hours from time to time then send my KYC to another company just for the sake of paying with crypto.

The decision for the game Juventus-Napoli has been delayed to next week, typical Italian thing.

The rule was clear if Napoli wasn't on the game the result must be 3-0 for the opponent and 1 point of penalization.

Rumors are now to "play the game and take 1 point of penalty".

What a shame typical Italian do whatever you want "thing".

Press release from Square:




The MicroStrategy idea is slowly trickling down the Street.
Slowly at start, then all of a sudden!

Probably yes but actually the situation in Italy is better than UK France and Spain.

I never want to wish any thing bad on a person especially person who is involved in BITCOIN. 

But this man had it coming with his statements and predictions.

I think over the years he has made more enemies then friends and thats never a good idea.

Players are tested every 4 days in Italy and before every match.
So far we have 0 positive in Juventus so what the other user was posting was a fake news.

Anyway today they found 2 positives in Inter.

That is common thing in Italy.Supporters there will never forgive their lead player if he decides to go to another team and there are a lot of cases like this in Italy.The only player they respect is Francesco Totti who spent all his career in the Roma team of Serie A and people still love him today while his substitute which was going to be Daniele De Rossi left Roma and people still haven’t forgive him.

This is the point. COVID was not a temporary effect on the economy. But a permanent distortion that will hinder for many years the growth of economies, also given the heavy burden of the debt we are playing off today.

The point is that numbers are not picking up fast enough. There is an high auto-correlation in employment numbers. To put it differently: there is an higher chance for business that didn’t hire recently, not to hire the next month. This is why a strong and fast rise in employment number is crucial.

Federico Chiesa is very close to sign a contract with Juventus (a 2 year loan contract with Juvetus). The deal will be made if Fiorentina can expand the current contract between them and Chiesa, that will be expired after the 2 year loan contract ends. It means La Viola don't want to lose Chiesa for free after the loan contract ends as well as their current contract with the player finishes at the same time.

Exactly. There has been a lot of debate and discussion about what should be done about vulnerable coins, including those presumed to belong to Satoshi, and the suggested solutions vary greatly. Everything from "Leave them alone and if/when they are hacked, so be it" through to "Irreversibly lock them so no one can ever spend them again", and everything in between.

theymos made a controversial post about this on Reddit a few years ago which you can read here: https://www.reddit.com/r/Bitcoin/comments/4isxjr/petition_to_protect_satoshis_coins/d30we6f/. He was essentially saying that if the coins are going to be stolen anyway, it would be better to just lock them instead. Although I can see the merit behind such a proposal, it does not sit right with me at all that the community is choosing to lock/freeze coins which aren't theirs. achow101 has proposed a solution I find very interesting in the last few paragraphs here: https://bitcoin.stackexchange.com/questions/91049/why-does-hashing-public-keys-not-actually-provide-any-quantum-resistance/91050#91050. Essentially it says to lock coins which are vulnerable, but provide some quantum resistant mechanism for the real owner of the coins to recover them, perhaps via a zero knowledge proof of knowing the seed phrase which was used to derive the relevant private key. This wouldn't however work for earlier P2PK addresses which were not derived from a seed phrase.

That's not accurate, and that article is also incorrect.

A quantum computer running Grover's algorithm can solve a hash in sqrt(N) operations rather than N operations. Although that article correctly states that SHA-256 could be broken in 2¹²⁸ operations instead of 2²⁵⁶ operations, 2¹²⁸ is not half of 2²⁵⁶. Half of 2²⁵⁶ is 2²⁵⁵. 2¹²⁸ is the square root of 2²⁵⁶. Sqrt(N) is a much greater speed up than N/2, but 2¹²⁸ is still far too many operations to be feasible any time soon.

Still, if you read my post above, breaking hash functions is not the concern with quantum computers - breaking elliptic curve multiplication is. Quantum computers can speed this up exponentially, meaning all coins in P2PK address (including ~1 million coins thought to belong to Satoshi), and all coins on addresses which have previously been used, are vulnerable.
