Thank you for letting me know! With the current price of BTC at $26,000, 0.9 BTC would cost approximately $23,400.

If you earn $500 a week and save $250, you would be saving 50% of your earnings. To earn $23,400, you would need to work for approximately 47 weeks (23,400 / 500 = 47).

Again, it's important to keep in mind that the price of BTC can fluctuate greatly, so it's important to stay updated on the latest market trends and make informed financial decisions.
