They are not the only ones that are making use of Blockchain. Facebook has released their own cryptocurrency and some has been saying that Amazon will likely be accepting the Facebook libra coin for purchase on their online shopping site, because the libra coin is from one of the biggest names and it is also a stable coin. Also I have seen people who are saying they are not going to make use of the Facebook coin because they are believing that it will be another strategy for Facebook to be tracing their moves online, like knowing where they are spending the coins and what they are buying with it.
