And since you are bitcoin users/experts,
Bitcoin users? Yes. Experts? I doubt it. Yeah there are still some that remains but this forum used to be filled with members that are experts in bitcoin but things have changed. This forum now is mostly filled ICOs shitcoins, spammers and scammers. But yes, you came to the right place to ask that survey. All of us here have used bitcoin somehow and all of us here must have a reason why we chose to do that.
Why not to choos bitcoin? It is so helpful in many aspects of my life especially in the financial aspect of my life.

It helps me also to give money fast or in payment because using ibitcoin the transaction is so fast enough to satisfy me.
