The biggest ad I've seen for bitcoin till now was done by BitPay, providing money and getting the Pittsburgh bowl (Football College) named the bitcoin bowl, even though that bowl isn't the biggest but the word bitcoin was mentioned in an astronomical scale.
Since then, there were few ads for bitcoins that I saw, but I didn't see anything as impressive as that.

I am trying to achieve future purposes from bitcoin generally of course, Planning to keep these as an investment and wait for an improvement and rise and afterward using it to buy items for good value. And I am not spending it because I believe that the price of it will pump more in the following years and grow generally with time, hence waiting for the best price.

Using a combination of 1) a paper wallet + a USB wallet as an emergency, both are encrypted with a pasword confident I could remember, 2) a safe desktop-based MultiHD wallet for quicker transactions that need to be conducted routinely like payment for services and paying for gift cards.

it doesn't look like that at all! I don't understand where all this FUD is coming from?
In regards to usage, the vast majority and still using bitcoins, some even exclusively, the price of bitcoin has had many jumps as big as or more than Ethereum, also the media coverage is more than 90% focused on bitcoin and ETH just shares the rest with Doge, LTC and the rest...

And now it's back to $2500, it's not wrong to buy at any price at the moment because we don't really know the direction that it will move into, the price could very well reach $3000 or drop down to $2000 or lower, people "us" don't know exactly when the train has reached the highest point RN.
