Just download cashapp on your phone and put in your your info/debit card you'll be approved to buy bitcoin almost immediately. Then once you have the bitcoin address to send it copy it into your clipboard. Next put money into your cash app balance using your debit card. Then click the bitcoin 'investment' button to buy the amount you need/cost of whatever. Then paste the address you copied. Then send and your done. If You do this within like 10minutes or so you may lose like a dollar or two, no big deal it doesn't fluctuate to hard. Hope this helps.
