There definitely are a lot of changes you have to make.
At first, when Bitcoin was known it wasn't that popular, is wasn't worth a dollar, approximately $0.28 and at that time it didn't mean alot to some people. But now Bitcoin has gone a long way in enhancing; they came up with an idea and developed an application which some people(not everyone) engaged their self in; but this didn't favour most of them (the people that joined the app) Why? This is because in that application you have a 50 percent chance of winning and also a 50 percent chance of loosing every thing you put in the business (application).
Bold: You've contradicted yourself here. It cannot be known but non-popular.
Underline: When was it approximately $0.28? Bitcoin launched as a completely free coin; exchanges paired it against fiat and other cryptos and that's how it started gaining actual value.
Italic: 50 percent win/loss chance? What exactly is this about? To me it sounds like either a Ponzi scheme or gambling.
Advert: As I said Bitcoin is well known but not to everyone known the capability of it. Advertising of it on televisions, radios, posters, printing fliers, magazines, signboards e.t.c. So that people will see the capability and growth of Bitcoin.
Having marketers: We need marketers not just any but qualified marketers who will go around telling people about what Bitcoin can do or what Bitcoin has done. This will promote Bitcoin and other Crytocurriencies.
Writers, bloggers: We have writers, bloggers among us they can also help in the growth of Bitcoin by writing on their blog page and Puting images or a short video of/about Bitcoin.
There's no need for teams or anything for BTC advertising to be done. In fact, a lot of us are advertising it one way or another every day and for free. We don't have or need "marketing teams" of any sort. We're decentralized, and marketing requires money that can be used for development instead. Whoever is interested in BTC doesn't need to see Bitcoin advertisements constantly.
Partnership with other popular companies
Partnership? Are you trying to say that larger companies should adopt BTC? That comes naturally. They'll go for it whenever they feel they should do so. Trying to convince a company to adopt BTC could go wrong if they don't meet expected results and decide to remove BTC later on.
I agree with @mk4. Feels like you've made the article in a rush.
