I think Bitcoin will prevail as a payment method. A lot of people are focusing on Bitcoin price, but Bitcoin is still a good technology. It is the best system out there for payment transactions and store of value (in other words, currency).
You don't need to register, you just need a secret number to receive bitcoins. A lot easier then other payment methods.
You own your money and no government can take it from you with inflation or a failure of banks.
It is decentralized and open source, so it is secure and private. Security of every Bitcoin transaction is independent and of each other and at highest level.
In other payment methods, you hack one entity and you hacked all their users. (Paypal just had a breach this Friday).
It is simply objectively the best. Fairest, fastest, easiest to use, private and most secure. It isn't just the best, it is 10 times better then anything out there.
Bitcoin as a payment system, In my opinion, the one who benefited most is the trader. In this kind of payment system, the sender is the one who pays the processing fees while the trader paids nothing.
It allows you to purchase items abroad fast and easy without currency conversion.
And I think that in this system, users of bitcoin can conviniently pay any bills just by clicking. You can save money and time at the same time.
I like the idea.
