I don't trust anything that big tech, Bezos or Amazon are saying, and they always have some hidden motives behind everything they do.
They hired some blockchain people few months ago, and there are some rumors they are working on creating their own token to be used instead of Bitcoin.
You can imagine that they will control supply and everything else related with potential amazon token including some kyc verification, and for Bitcoin they can always have some stupid excuse like high fees, etc.
After the setback we received from Elon Musk, I don't really trust these people. They just want to maximize their profits. And for that purpose, Bitcoin is not very suitable. Elon is now planning to roll out his own shitcoin with a near 90% premine, and this may be the same route used by Amazon as well. These guys benefit more from a cryptocurrency which they can control and manipulate, when compared to the case with Bitcoin which can never be controlled by a single central entity. Anyway, for now, let's enjoy the market rally.
