The Tesla and Amazon events have a certain impact on Bitcoin. Tesla manipulated the Bitcoin market through his comments. When rumors about Amazon accepting Bitcoin payments appeared, the price of Bitcoin immediately showed an upward trend. They have a lot of influence, their fans will follow what they do, which drives up prices. Bitcoin prices are easily affected by these external factors and change.
I also believe that whales, along with large corporations such as Tesla and Amazon, have a significant impact on cryptocurrency. They have a large percentage of the circulating BTC in the blockchain, so they have the ability to manipulate, as seen recently. Elon Musk has created a ruse that cause a market crash in BTC, resulting in a bear market. These kinds of things should be taken into account because they can have a significant impact on the price of BTC and, of course, other alternative coins.
But if you're asking about BTC relying on them, of course, it's not.
