Is Bitcoin surge driven by paid-publicity (similar to US election story)?

Help me understand why this strategy would fail.

Let's assume I got 100M$ with me.

Step 1: Purchase 70M$ worth of bitcoins.

Step 2: Spend 30M$ marketing bitcoins as the next big thing

Given that bitcoin is a pretty good product, the additional marketing would help convince people to invest in it.

Step 3: Convince 1000 other 100M$+ net-worth individuals to do this.

Step 4: Let it surge. Wait till the combined worth of 1000 investments above is At this point there is about 30B$ of marketing budget. 3 times of what Samsung spent on marketing in 2016.

Fake news, facebook & twitter ads that influenced US elections proved that it's possible to do something like this. At this point, it's worth mentioning that 'Bitcoin is a great product' unlike the former case.

Doing above is possible with any public stock but it's probably illegal. With Bitcoin I am assuming there is no such check.

So what's stopping people from doing this?

Anyone else thinks this is how it's happening already?

A good product for what, exactly? Fast, decentralized, small monetary transactions? Because right now BTC is pretty awful at that.

pump and dump without all the regulators coming after you post dump

If you can convince 1000 people to invest $100M each with just $30M in advertising, you're some kind of marketing Einstein of our generation.

Why pay for the marketing when every major news outlet in the country will continually cover the story as the price continues to rise wildly and as major financial institutions get invested?
