1  Bitcoin / Bitcoin Technical Support / Bitcoin Core Startup Failure on: March 04, 2022, 12:40:55 PM
I have been running the bitcoin core successfully for months on an external 1Terabyte drive connected to a MacBook Pro.  Accidentally, the hard drive disconnected from the USB port. I now get this error:

  ./bitcoind
  dyld: Symbol not found: __ZN5boost10filesystem4pathdVEPKc
  Referenced from: /Volumes/Brown_Fam_Back_Up/bitcoin/src/./bitcoind
  Expected in: /usr/local/opt/boost/lib/libboost_filesystem.dylib
 in /Volumes/Brown_Fam_Back_Up/bitcoin/src/./bitcoind
  Abort trap: 6


Any ideas to repair are greatly appreciated.

I have searched the forum and there is talk of using a file called Bitcoin-Qt but I cannot find it.
Also, where are the core data files kept?

Thank you,
2  Economy / Service Discussion / Bitcoin Daily Price Download from an API on: July 12, 2021, 02:41:06 AM
I would like to be able to pull historical daily bitcoin price from an API like coinbase.
I created this simple python file to retrieve realtime bitcoin price and print to screen every two seconds:

Can anyone direct me to a URL that pulls historical daily bitcoin price so i can save it to a file?

from time import sleep
from datetime import datetime
import requests
import json

while True:
    response = requests.get('https://api.coinbase.com/v2/prices/BTC-USD/spot')
    data = response.json()
    x = (data["data"]["base"])
    y = ( data["data"]["amount"])
    print(' =======================')
    now = datetime.now()
    current_time = now.strftime("%H:%M:%S")
    print("Current Time =", current_time)
    print (x + ' ' +  y)   
    sleep(2)
3  Economy / Exchanges / Fees for Buying Bitcoin on CoinBase on: April 23, 2021, 01:58:15 AM
I am trying to understand the fees for buying Bitcoin on Coinbase. 
1. Their website talks about a 1.49% bank account fee. 
2. It also talks about a 0.50% spread fee for trades.

Do both 1 and 2 from above apply if i buy from my checking account that is linked to Coinbase?

Thanks,
4  Bitcoin / Bitcoin Technical Support / bitcoind - what is it doing? on: March 29, 2021, 04:52:48 PM
Sorry for the dumb questions but as a python and JavaScript programming I am learning from well acclaimed book: "Mastering Bitcoin".   I have downloaded the bitcoin core and ran the file: "bitcoind"  per the instructions in the book.  Now I have an app bitcoind, running nonstop.  Can anyone tell me what it is doing?

How do I stop it?
