Only the uninformed will believe Icloud to be a preserve place for security. Delete may not be the best measure but I want my mind to out of that place and any sensitive data. I don't have anything on the private keys, the least I worry now is the privacy I have exposed but that's fine. I wish internet could have futures to disable many things.

The idea of Icloud storage is only good gallery and Media, passwords private keys and seed  phrase or recovery seed shouldn't be store in such places.
I was going through the tweets thread and my mind was a bit scared with things I have been hiding on my Icloud right before I took my privacy serious. So I checked my Icloud and there was an Altcoin wallet I installed back then and ignorant me, I backedup the private key to the Icloud( the developers enable the option backup to my private key to Icloud).



The wallet was no longer on my phone and I decided to installed the app on my device to test the magic. I installed  the app, I allowed the face ID and the next thing that pop up was the options to login with my previous account or to import new account. The app had access to my Icloud.



I selected the previous account and that's was how my previous staking transactions pop out, there was no nothing in the wallet as I have already sent them back to an exchange.

I have did one thing with the Icloud backedup private keys....DELETE



The data has been deleted from my cloud. Such things are not meant for any third party, it should only be on your custody, you can mistakenly lose your password to another person, your Apple ID AND PASSWORD will make you loss everything, including privacy once  anyone has access to them.
You can see the amount of stolen ethereum that was announced by Metamask, is possible that such exploit is still going on. while Apple has promised you that your data are encrypted, note anything encrypted can be decrypt.
Stay safe.

There was already an open similar discussion on why some centralized exchanges are yet to implement Lightning Network and many key points were discussed.




I just got this image from the net, the last month web traffic of centralized exchanges, the two leading exchanges are Binance and Coinbase, it is not all the users that may have withdrawn through bitcoin but imagine if one-third of that population waste $20 on bitcoin withdrawals, that's gigantic money for them.
The reason why  I see the call for LN adoption by centralized exchanges could be that they are trying to get the attention of users who have been wasting much on fees on big exchanges and that's cool, who knows Binance and Coinbase may change their mind to increase the adoption.



There is no point in opening and closing channels all the time, one can save fees by using one and use it as long as you want, you cant run attempt to play foul in LN

Checksum use SHA256 as a fingerprint of any data you input. Let's say you have data you want to hash.
You have this data : 4a78e8d3d738ad1f9026009cf394bf7a8c86901b
The SHA56 result gave you: 92036ae0ca79f5b8c10bc9f951b244833be9a5771b00fa7fc63db711f0b6d9fd

The checksum becomes : 4a78e8d3d738ad1f9026009cf394bf7a8c86901b92036ae

It is convenient and standard that way for any software to detect any missing data than taking the last 4 bytes (f0b6d9fd)


The answer is NO and security-wise it is not safe, if checksum could be used to recover missing data, bitcoin will not be safe as anyone with a few data of private keys can easily exploit that to detect other full private keys details.

NOTE: SHA256 is an irreversible process, you cannot go back to the original data.

There is something wrong with your testimony man!
You took multiple lond of LTC and you didn't explain anything about that. Did you deposited LTC to make more LTC or was that futures?
If you trade, you are against or for other traders, it doesn't concern the brokers, they are using other traders to settled you and they should be lucky to have great traders like you, it is weird to cut you out of their leader board.
Some exchange/brokers used successful trades as ads, why are you exempted.

Million years ago, that is what I was we were told. More like a fact than theory.
Bitcoin has been a liberty to some people, almost every part of the world has heard about bitcoin it just that not everyone will have that opportunity to get it.
Either with bitcoin or not, the world still remains the same. When there was no bitcoin, there were war, there were famine, natural disasters, global warming and now that we have bitcoin, these things are still available everywhere. Apart from global store of value and hedge against inflation preserve, others things still remain the same.

Have you ever withdraw bitcoin from a centralized exchange? If yes, then you know the answer already.
Centralized exchanges are business opened group of people, you want them to stop having access to your flat rate of 0.0005btc charges they collect from withdrawals, their generated revenue will be reduced, you don't want it, don't you? 

Centralized exchanges are known for milking users, the idea of lightening will remain untapped by this guys. Common Bech32 address that has been used by many wallets has not been implemented by this them talk more of LN. It's a fee killer and bad idea for them.

There is no smoke without fire. I can only see the offer he is giving to get all the shares but his reason for acquiring Twitter is not convincing. I know he is Bitcoin pro and a maxis, but wait a minute. You don't just take a platforms and reforms it easily, you have to know limit and when a spade is spade.
Twitter is a home of crypto investors but I can say boldly that is not everyone who is on Twitter that has use bitcoin in there life.
I know he is an Ambitious man but sometimes, it is best you leave things the way they are and I personally haven't really experience any issues using Twitter since I registered an account unlike Facebook that is myopic and self center in their ads.

We all have idea but what kill it faster is funding. If you don't have funding set up from the initial stage, it becomes a problem on the long run. Permit to ask, was there an initial planing of funding or you just create the casino and later discover that you will need funds to bring it to reality?
I'm interested in that p2p part where you made mentioned of an agent. I get scared anytime I heard of the word Agent, in any field, I find it difficult to trust this guy's as they worry me with how most agents has run away in furious moment. Do you trust your agent? This is people's money, you don't want the government to start chasing you for offense you didn't commit.

The margin between Real Madrid and Barcelona is a 12 point difference, for them to cover up such gap, Barcelona need to win at least 4 Matches, though there last matches were magnificent that even Real Madrid couldn't stand them but it is going to be a heavy task if they really want to demonstrate the king of Spain.
Manchester city is always know for giving Real Madrid some lessons but with their current trend, I don't think they will give up to Manchester city, it may end up with PK.

Leverkusen isn't kidding either, their last matches were all drawn until their last encounter. Leverkusen has everything it takes to beat Leipzig, they are both in a tight spot right now. Leverkusen is struggling with 8 points to catch up with Dortmund, while Leipzig only needs a single match to be a win to make it to the top 3. Freiburg has been encroaching gradually like a snail, which is why both of them are uncomfortable staying there. If they both draw, nothing spoiled they can still face their other opponents to search for goals.

They should worry comrade, having you removed from the tournament is painful and it was even a quarter-final for that matter. They didn't make it to the Champions League last season but were able to do into the Europa League, it was an opportunity to shine over a small team but I think many people underestimated Frankfurt. Top 4 Laliga is certain but trust me when I say Barcelona wouldn't take the Laliga cup, Real Madrid has put their body and soul on that cup.

If I understand your question, you're trying to see the open price of bitcoin at every candle. Here is an example on how to enable and disable it anytime you want.



Click on the three dot illustrated by the arrow in the image above, you will see a drop-down menu, click on the settings and you will see another sub-menu and select status line.



Finally, you can tick OHLC( Open, High, Low, Close), with this you can enable the open price of any coin and you can play around with other indicators

At the strike is wrong, the custodial address you mean. Centralised exchanges are becoming a problem but of course to only those who cannot do without them. You cant satisfy centralised exchanges, even the KYC they are demanding is not enough for them when a problem ensued.
There is always an alternative to centralised exchanges right from the very day AML has been trending, use exchanges that don't require KYC that allow withdrawals and it should be done bit by bit, don't deposit all your life savings on anyone custody, your money and privacy are only save when they are on your care.

Before you create a wallet, you know the condition and your friend is aware of how important a seed phrase/recovery phrase is to access your funds. To spend any bitcoin locked on any public key, you need the private key to authorised the transaction, now tell me the alternative you are talking about, this is the security measure of bitcoin and there is no any alternative to this unless you have a backup of your p.keys from the beginning of wallet set up.


There is one alternative to access your private key as I have replied above, properly backup your seed phrase at the initial set-up of your wallet, and inscribe them on a metal plate for maximum security against fire disaster.


Biometric is just an extra layer of security more like password, it doesn't have anything to do with seed phrase. infact most wallet allow you to encrypt your wallet with a password so that any bad actor wouldn't have access to your seed phrase or when someone try to export your private keys but the password encryption is not enough. This is where a passphrase come into play, it helps you to secure your funds incase when someone get your seed phrase, without it, the wallet will be empty.

 

They didn't choose that life! I was having a conversation with my Dad and cycle of his friends why they didn't invest in safe assets when others where investing and putting money into Gold and some stocks, the reply I got was they weren't aware as they were caught up by idea of going to school, graduate with good results and find a good job that will sort out their bills, they didn't realize that they have been working while there pay check was becoming worthless everyday.
Inflation has been there since the beginning of money, the commercial banking system and central banks knew ths eating down economy but they will rather continue to hike interest rate and print more nonsense paper to stabilize the failed system they created. The circle continues, print, print and mint.
Cryptocurrency may be volatile but is the volatility that important if your assets is been preserved overtime, get a portion of BTC or be prepared for inflation and stop ranting.

Twitter isn't just home for cryptocurrency investors, it harbour every business owner you see on the planet, it has gain a such magnificent impact in the society, there microbloggling platform is most visited when compared to Facebook due to some data protection and users identity thefts, people can also communicate around the world but you Doge cannot do all these things and not just that, the company wouldn't sit and allow him do such kind of thing ( I know you would say they added bitcoin, it's more better compare to meme coins) by allowing him use $41B of companies fund to buy Twitter.

Why did you rule out Barcelona if you think Sevilla will be having hard times in making it to the Champions League? They both share the same points(60). Sevilla next meet is with Real Madrid and it's certain that Sevilla will loose to them, the same goes for Barcelona. Frankfurt and Barcelona doesn't have much history but their last match was horrible, I didn't expect Barcelona to draw and settled for 1-1. By next week, things will become more clearer.

The last time Villarreal faced Liverpool in Europa League, it was a flawless win without much stress. They aren't match for Liverpool but you know it is semi-final, they wouldn't go down without a proper fight in the match.
Manchester city struggled to qualify yesterday, if not for their first Home match, they wouldn't have made it (PK is 50:50 outcome). Now that we have only Spain and England remaining in the league, let's get some entertainment.

Betis performance in March was quite bad, but they have improved this month. If they can keep this up, they have a good chance of reaching the UCL. I'm impressed that their statistics are very similar to Atletico Madrid's is just that they are ahead of Betis with 1 goal and 1 point, they shouldn't sleep now because, with a single won match, they can easily secure the spot but if they fail, Real Sociedad will push them down, they could both have a difficult time with their next match (Real Sociedad - Betis).
