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.
I choose to invest in Bitcoin because this is the mother of all crypto currencies. The price is keep on increasing from early this year until now. The volume of capital invested is huge and the demands of investors are keep on rising because they believe in the performance of Bitcoin. I've seen a lot of people have earned so much as they've invested to Bitcoin. Moreover, it helps us to make our lives easier and better like bills payment thru online using Bitcoin as payment. So invest now and you will see how much you will earn in the future.
