There are laws to help deter that from happening.
Do you really think this is even remotely true? Bitcoin is not a regulated investment vehicle. If anyone buys more than $1 million in Bitcoin everyone knows about it. The price even goes up.
There is nothing that really deters a company such as Intel to get into Bitcoins and ruin the system.
Investors would greatly deter Intel from wasting money getting into Bitcoins. The company would lose billions, not only in research and development with manufacturing fees, but in market cap as their stock holders would sell everything for the knowledge that Intel clearly doesn't have a clue what they're doing. Since Intel probably does know what they're doing, they won't touch Bitcoin. You're stuck on a non-issue.
If Bill Gates didn't like Bitcoin, he wouldn't announce it and would likely do it through companies by giving them money to help bring about its downfall.
It really sounds like you don't even know who Bill Gates is and you just recognize the name as having a lot of money.
I'm sure if Microsoft decided to go into Bitcoin, that news wouldn't be taken too well with the opensource community.
Like Parsifal asks, why on Earth do you think this?
