Is there a free API that provides the historical market cap of the global crypto market? I see that coinmarketcap has snapshots on the website, but historical market cap is at least not in the free API tier.

Is there a single webpage that lists the current transaction fees for the major blockchains, like BTC, ETH, solana, avalanche, matic, BCH, BSC, etc?

I found that post, but I find the instructions ambiguous:


Setup a new secure Bitcoin wallet - but we are dealing with 2 wallets for 2 new coins. I am assuming that if the original wallet was electron cash, it means to set up a new electron cash wallet?
move all your Bitcoins - But since step 2 says to wait until they are confirmed, I am actually sending bitcoins from the old wallet, which is out of date, to the new wallet and a new address? Because "move" could also indicate to just transfer the private key to the new wallet?
 

As I mentioned in the original post, I had BCH in the electron cash wallet, 2.9, and I'm looking to claim the BCH/BSV.

Link looks out of date as it doesn't mention BSV, I was wanting to make sure there weren't any forks off of BCH or BSV since the BCH/BSV fork.

I had some BCH before the fork, firstly how do I see a list of BCH forks? Maybe there are more besides BCH and BSV, and have either of them forked since?

It is in electron cash wallet 2.9. Can I do the following:

1. Install new version of electron cash.
2. Install ElectrumSV.
3. Import private seed into new electron cash.
4. Import the same private seed into new ElectrumSV.

Am I then done? I am not sure what the issue of replay protection is, but it doesn't apply to me, right?

According to this article they got the hacker's private key: https://californianewstimes.com/us-says-it-has-recovered-large-portion-of-colonial-pipeline-ransom/383269/
Unclear how, but it mentions some servers being seized, so maybe they got access to a physical device. Or perhaps they got malware onto the device or there was a cooperating exchange.

Why are the prices higher on Defi platforms, isn't it up to ethereum and not the platform?

I just looked at depositing in a lending pool and it gave an estimated price of 0.00834ETH which is ridiculous. I did not continue and am not sure if there would have been another fee after that?
And then more fees when withdrawing?

Let's say I want to make a large transfer to an exchange. I am sure to verify the receiver address. However, if the exchange made a mistake somehow, all the bitcoin would be lost forever. So does it make sense to send a small amount first, confirm that they receive it, and then send the rest?

Because I have also heard that each address should not be used more than once.

How much does one get for staking CRV?

For the Defi protocols like AAVE, I think Compound is another, if you lend your crypto for interest, are you going to get back the same crypto when you withdraw it, or otherwise will fungibility be an issue?

Eg if someone has dirty coins and they get them into these platforms, am I at risk for getting some of them when I withdraw the coins I put in to try to get interest?

Same thing if I use one of them to take a loan, and then try to deposit it in a centralized exchange, is there a risk it could be blocked?

But is it really going to be thousands of millions of people or will it be a few hundred people in each country who are willing to root their phones to install apps, since all the wallet apps will be removed from the app stores? Haven't we seen how easy it is to control the public in every country?

How are governments finding it difficult? It has been quite easy in China and the US, eg. Most exchanges have stopped accepting US customers and all the US exchanges are likely going to have to report transactions to the government (it was just proposed yesterday). They are also proposing new, higher taxes on cryptocurrency, which are higher than taxes in other areas like real estate.

Yes obviously, but I am posting the perspectives of government, not what's actually the case. How is bitcoin a privacy coin when the blockchain is public and 99% of transactions are not layer-2?

I would NOT do anything or be in a hurry, as people have pointed out above, you don't want to make a mistake and destroy/lose a lot of money. You have been given some excellent advice above, I would re-read those posts many times and do your own research on the terms they have mentioned, look up each one in a search engine to understand what is 2FA, what is a hardware wallet, read about the specific hardware wallet you have, and so on. When you have questions, search this forum for the answers or make new questions.  

I would absolutely NOT recommend going to the police or to the family/friends of your uncle, you have no idea what the police are going to do, you don't know that the friends/family of your uncle are trustworthy or if they just want to take the money for themselves, or if they even know anything about cryptocurrency. Obviously he confided in you for a reason, because he trusted you.

Someone mentioned finding someone local to help you, I think that is way too risky because they will pretend to be nice and helpful but will want to steal the money.

Also don't answer all the random PMs you are getting, because they are probably scammers even though they seem nice and polished.

Don't mention to anyone in-person, any friends/family, etc, of what was left to you, as it is a risk.

If someone refers you to someone trustworthy online who can give advice, vet them yourself, don't just go with someone's recommendation.

China just made statements cracking down on mining/trading, the US proposed new reporting requirements for transactions, the concern of crypto being used for tax evasion and illegal activities, the Bank of England governor recently said bitcoin has no value, European officials have often made negative statements, and there is always talk of bans in India. It was just reported on the news that Hong Kong is going to announce a ban for retail trading of cryptocurrency.

It's obvious that countries haven't considered bans in the past because they didn't consider bitcoin to be a threat, and it gets harder to ban the longer they wait because of the negative effects on their country, but the possibility remains. Also even if it were not banned, governments can monitor all activity because basically everyone uses centralized exchanges and the blockchain is public. They can tax it at whatever rate they decide to. It is just not conceivable that ordinary people are going to install applications on rooted phones to be able to continue to use bitcoin in the presence of a ban.

So what would the future trajectory of the world look like after that? I guess the price would fall precipitously, probably under 5000 USD or more likely 1000. Are people still going to want to hold it when the government can always come after them? I don't see how any small underground activity like paying your hairdresser in crypto, or even sending money to family/friends internationally is going to be able to sustain the viability of bitcoin, nor how the vast majority of the population can be convinced to use it in the face of government FUD.

One thing that does not seem to a be a concern is mining, because even if governments outlaw and can find ASICs and farms, the mining can always shift to use less electricity, fewer ASICs, etc.

One drawback is ppl could sell their private key. There does not seem to be any way around it, except to embed something about the person's identity (eg, name) into the message, and have the person show their photo ID to the business. But that is a tradeoff of privacy for security.

I think this is a really good solution. It's low cost, secure, and can be used internationally. I would include the type of vaccine (eg, Sinovac, Pfizer, etc) because it might turn out that some of them do not work. Also one would need to keep each message, for the first vaccine, second vaccine, booster shot, etc, and the business could look at all of this information to determine if a person is 10 days out from the 2nd vaccine (if it is a 2-vaccine series).

Thx, found the relevant passage in the contract:

From the other language in the contract you are right, the NFT is simply the title to the digital artwork, much like a real estate title proves ownership of a parcel of real estate. What makes this bizarre is that the digital art can be duplicated, unlike real estate and the land on which it sits.

The last part,
is done by including a link to the actual online artwork in the token meta-data, which is unalterable.
https://www.businessinsider.com/what-happens-to-digital-art-nft-servers-shut-down-2021-3

In case that site stops hosting it, the owner can always create a new NFT with new meta-data.

Presumably they also included a hash of the digital artwork in the token.

Can anyone explain with the recently sold Beeple NFT in particular, what exactly was being sold? Is the artwork itself stored in the ether ecosystem on the blockchain, or is the token a hash of the artwork, or is the name of the artwork in the metadata of the token? I have not found any articles that explain it.
Also where do I find what rights are conveyed with the token? What would allow the buyer to re-sell it?
