search the Internet and explain why some organizations are accepting and other organizations are rejecting the use of Bitcoins as a standard form of currency.  Your paper needs to identify two major companies that have adopted Bitcoin technology as well as one that has refused accepting Bitcoin as a form of currency. Be sure to discuss each organization, how they adopted (or why they won't adopt) Bitcoin, and what recommendations you have for them to continue to support Bitcoin (or why they should support Bitcoin).

Deliverable Length: 12-15 slide PowerPoint presentationOBJECTIVESWith the introduction to management complete considering the illustration of IoT devices, infrastructure and architecture we can now proceed to their core presentation on how IoT devices typical perform the communications. Prepare a 12-15 slide presentation regarding the following topics: Identify how IoT devices typically connect using the Internet through the IP (Internet Protocol) stack. Discuss the specifics of this communication method. In addition, describe the memory demands on the device to use this communications method. Define how IoT devices can also connect locally through non-IP networks, consuming less power, and connect to the Internet via a smart-gateways Identify how Non-IP communication channels such as Bluetooth, RFID, and NFC are used to support IoT device communication Identify how 6LoWPAN, incorporates IPv6 with low power personal area networks, and the types of communications/data transfers it supports.Make sure to expand on each of the topics in the Speaker Notes with 3-5 paragraphs of info for each major topic in the notes.Use APA format on each slide or in the notes to support all technical assertions.
