I want to buy bitcoin for the purpose of making a transaction with a business that specified bitcoin. I have a Copay wallet on my desktop, but after doing quite a bit of reading, I'm still not sure about where to go to buy them and how to get them in my wallet. I would be paying with my Visa debit card or through Pay Pal. I've already calculated the amount, which would be 0.025 bitcoin which roughly comes out to $50 US. I know I have to click receive and then to 'request specific account', which takes me to a place where there's a QR code and an address. Not quite sure what the long alpha numeric address is for and about how I purchase the bitcoin and get them into my wallet. I see there is a slower and faster way to do this. Fast is good, but I"m in no particular hurry If you can help, I think that I'm almost there. I"ll keep reading in the interim.
Thanks so much,
