Thank you for this opportunity to give my opinion on this technology that is as big as the internet. BlockChain technology has many possibilities for application and will surely improve the world by offering more trust and transparency in both business and social relationships.

Bitcoin is a good example of this. Through it we can make payments safely and quickly, and all transfers are available for auditing.

Technology has evolved a lot, and Bitcoin is an example. Certainly the approval of EFTs for Bitcoin will give the market security to invest and contribute to the advancement of technology.

No doubt it's a great time, and I believe this will happen.

Technological advancement can not stop.
