Questions about btc

So, I was thinking to make a shop (no more details :P ), and I asked my self is btc popular?
Will I'm some money by btc?
Are there alts? (no paypal)
I won't ask more. I just found that I can create a VCC that accepts btc so I'm happy I can use my btc wherever I want know. And yes I don't use paypal anymore because of scammers. One guy in ebay scammed so I'll never prob use paypal ever again.
