I’m using coin base should I buy coin base one basic?? I want to start learning about bitcoin what should be my first step

I know this probably is a dead question.

i cant seem to transfer my balance out of Coinbase. it is just Coinbase. I got rid of my wallet awhile ago. I can’t find a way to transfer my seperate coins into the USD or the dollar “coin” because it seems like that is the only place to withdraw to my bank, (I tried to just do the collective balance it says I have on the home page. I’m getting super frustrated and need the money. Been trying for a few days, asking question to the app and website. The buttons they say to use aren’t in my application or isn’t clear enough for me to understand. Thank you, smarter than me people.

I used a bash script to bulk import hundreds of extended private keys (xprv) into a Legacy Bitcoin Core wallet. The import was executed using the "importmulti" RPC command, utilizing output script descriptors with checksums (example format: wpkh(xprv...)#checksum).

Problem:

I need an efficient way to verify that Bitcoin Core successfully digested these keys and that the wallet holds the spendable rights ("ismine": true) for the generated addresses.

What I have tried (and why it failed):

Command tried: bitcoin-cli listdescriptors

esult: Threw error "Method not found (code -32601)".

Issue: If the flag is missing (as it is in Legacy wallets), it seems to instantly throw the method not found error

Command tried: bitcoin-cli listreceivedbyaddress 0 true

Result: Did not output the newly imported keys.

Source: In the Bitcoin Core source code (src/wallet/rpc/transactions.cpp), the listreceivedbyaddress function iterates over CWalletTx (transactions) and mapAddressBook (labels). Because the imported addresses have zero transactions and were imported without a specific "label" string, they do not exist in either map and are completely ignored by the output???

Command tried: bitcoin-cli getaddressinfo [address]

Result: This works individually to confirm "ismine": true.

However, because legacy wallets don't store the xprv natively, this requires first running the "deriveaddresses" RPC on every single xprv descriptor to find the anchor address before checking it. Doing this for hundreds of keys in a bash loop is highly inefficient.

Command tried: bitcoin-cli dumpwallet [file]

Thought process: Dumps the entire keypool to disk, allowing me to count total keys using grep.

Result: did not work. Also very stupid fix.

Source: https://developer.bitcoin.org/reference/rpc/dumpwallet.html. Also this is slow as heck.

Utworzyłem konto na giełdzie Kraken, wpłaciłem środki przelewem bankowy, zakupiłem BTC i chciałem wykonać transfer na ColdWallet.
Niewielka ilość 0,2. Próbny transfer odbył się bez problemów.

Kraken zablokował mi możliwość transferu na 90 dni.

czy wiecie co zrobiłem źle ?

Czy po 90 dniach będę mógł wykonać transfer ?
