When we make a payment with a note of $ 50, we are making a payment that is fast, cheap, and who does not require intermediaries. Fast, because the time for the transaction to be completed is the time to deliver the ballot to the seller. Cheap because because there are no fees for this transaction. No intermediary because it is not necessary that no other company involved in this process, not the buyer's side, or the side of the seller.
In electronic forms of payment, there is a major change in the relationship between buyers and sellers. If we take the example of a payment slip, it ceases to be fast, because besides the buyer have to do to go to the bank to make the payment, the seller will only receive the money a few days later. This payment also has a higher cost, since in addition to the cost of the ticket, the seller must have a bank account and the buyer sometimes has to move to pay it. Finally, there is always the bank intermediating the transaction, and sometimes, other companies such as Paypal, for example.
Understanding Bitcoin is simple. It is a digital technology that allows you to play in electronic payment efficiency of payment with notes described above. Payments with bitcoins are quick, cheap and without intermediaries. In addition, they can be made for anyone who is anywhere on the planet, with no minimum or maximum value.
The technology is gaining many fans worldwide. Recently Bill Gates in an interview with Bloomberg TV business channel said that "Bitcoin is exciting because it's cheap."
Today you can make donations in bitcoins to global institutions like Greenpeace or Wikipedia, or buy airline tickets on Expedia, or to enter into an apartment in Tecnica, all using bitcoins.
I believe it to be the most relevant technology being produced on the internet today. And it's just beginning.
