Problem scenario
You have been listening to Nietzsche's Will to Power. You heard the term "chandala." What does it mean?
Solution
The correct spelling is "chandala." This originally Sanskrit term refers to the lowest class of people (e.g., the outcasts or untouchables). The term "chandala" is considered a slur in parts of India according to The Pariah Problem: Caste, Religion, and the Social in Modern India by Rupa Viswanath.
Problem scenario
In MetaMask's dashboard, you see a cryptocurrency with a balance that does not seem correct. You click the three dots on the right of the balance and click "Resync Balance." It appears inaccurate (as you just sent more coins to the address of your MetaMask Portfolio). When you click on the cryptocurrency symbol, you see a "Holdings" balance that appears accurate. Why is there a discrepancy between the "holdings" balance of the individual coin and the dashboard's balance for this coin?
Solution
We do not know why this happens, but we found a solution. Close out of MetaMask entirely. Reopen MetaMask.
Problem scenario
You are coding in Python. For some reason your list is getting out of order. It sometimes works. But sometimes the last item is going to the first item. What is wrong?
Possible Solution #1
Re-examine your logic. Break things up into smaller lists and fewer variables for the sake of testing.
Possible Solution #2
Look at the different input files if there are any.
Are you using input from a file? Can you check every item of your list to see if there is a hidden new line character in it?
This could help you find it:
for item in your_list:
if "\n" in item:
print(item)If you use "".join(your_list) (to convert a list to a string), a hidden "\n" in a string in the list can create problems when you write to a new file. Processing text with varying input can create problems like this. You may have to eliminate the "\n" instances using Python.
Problem scenario
You want to avoid needing to go to a doctor. What should you consider?
Solution
Try to avoid stress or manage it well. This article says than 70% of doctors visits are from stress.
Problem scenario
There a non-custodial exchanges (that do not store your cryptocurrency). Is there a non-custodial wallet for your digital assets?
Solution
Yes, this term refers to a "cold wallet." We think the term "self-custodial wallet" is preferable to "non-custodial wallet" -- but the term "cold wallet" is more commonly used. Apparently in the cryptocurrency world, custodial wallets are those you do not physically control.
Problem scenario
You are concerned that if your have money in your Trezor wallet, someone could take control of your computer and steal the cryptocurrency from it. Is this possible?
Solution
No, it is not possible as far as we know. To send money from a Trezor Model T (and possibly other wallets), you have to near the physical display to push a button. With just the Trezor Suite (the application that can run on Windows), you would not be able to fully operate it. So someone has to be able to touch the physical wallet to operate it.
Problem scenario
You are setting up MetaMask for the first time. It says "First, enter the Secret Recovery Phrase that you were given when you created your wallet."
You read this:
Do not share your recovery seed with anyone else.
https://trezor.io/learn/a/how-to-use-a-recovery-seed
Do not keep digital copies of your recovery seed (this includes screenshots, photographs, emails, Dropbox backup etc).
You read this:
Importing your Trezor seed into a wallet like Metamask will reduce your security to that of a hot wallet, even if you later put the seed on another Trezor.
https://www.reddit.com/r/TREZOR/comments/nbo989/set_up_trezor_recovery_seed_through_metamask/?rdt=46267
Should you enter the Trezor 12 word recovery phrase as prompted to use MetaMask?
Solution
No, usually you should not.
If you have not used MetaMask before, you will be required to set up a wallet and generate a recovery seed. This recovery seed is separate and is not part of your Trezor and is not necessary if you only intend to use MetaMask with your Trezor.
https://trezor.io/learn/a/metamask-and-trezor
Do not import an existing wallet. Start over and create a new wallet for MetaMask.
If you already sent a coin to a Trezor address and that coin is not supported by Trezor natively, you may need to import your recovery seed into MetaMask to use the coin; in fact, after you do the import, you may need to import a modicum of a subsequent coin of that type of cryptocurrency to the address again to see the total balance in MetaMask. The subsequent coin could have only a nominal value, but that may be necessary. If you have not sent any coins that are not natively supported by the wallet, and you do not intend on using coins not supported by the wallet, to be secure, we do not recommend you import your wallet or give your recovery seed to another entity/party or software application (such as MetaMask).
Problem scenario
You installed the MetaMask extension on a web browser. You cannot seem to locate it or open it. How do you use MetaMask now?
Solution
Click on the extensions icon of your web browser. If you click on extensions or are viewing your browser's extensions and you do not see it, go to Extensions, and choose the allow option for "Run in Private Windows." This should make it visible for you (even if you were not necessarily opening a private window).
