You guys do realize that those companies do not hold Bitcoin? The more sales they have the worse it is. They instantly just convert to fiat. That's one of the problems of today.
Although you're right. People here tend to be pessimistic and panic often which hurts the price.
The real question is can we change anything about it?
if they sell someone must buy, the problem aren't those big companies selling like mad, but the buyers which are lowering their walls, and the fact that there are few strong buyers out there, the rest are just scared newbies
Must? No they don't have to buy. You do realize how Bitpay works right? If they sell more than people are buying the price is going down.
I'm actually disappointed that these large companies do not keep a percentage of the Bitcoins that they receive. They're financially strong, they could do it.
