It is not easy to define and pick the best payment gateway method for online payments. Multiple factors determine what is a good payment gateway like technology, support, fees, etc.

I would suggest https://www.puutwallet.com very secure and safest app

Bitcoin is not a company; it is not owned by anyone. It is a technology that uses a cryptographic method to exchange money. It is almost like a P2P Torrent system except what they share is a cryptographic currency.many of bitcoin payment gateways like for example https://www.puutwallet.com/

There is a huge list for bitcoin exchange, but I prefer Puut Wallet https://www.puutwallet.com/, an Emerging wallet had a great and fresh interface and was easy to use and extremely useful for both getting & exchange bitcoin from anywhere as well as for local transfers.

I'm using Puut Wallet App bcoz it's efficient and secure
