This is the time to look around and ask: What else can be done to sustain BTC growth? How to increase interest in BTC? Everything possible is already being done on the stock exchange. Where are the other growth points? Growth points in increasing demand and interest.
I don't think any kind of advertisement is needed to increase BTC. If people know what is BTC, How it works and why we need it, then the price will skyrocket automatically. Moreover, those who are consider btc as trading activities they always concern about the price. But the purpose of BTC is just for trading? No, It has various uses-case. It will be difficult to predict where the value of BTC will go if people become aware of it.
You certainly be thinking how it is possible this will grow big when it is all just about these things and stuff. Honestly, that is really hard but why we have witnessed such a huge growth in its price? And this is because people value Bitcoin more than these things and pulling the demand high makes the price shoot up. And this gives courage and interest to the community to step in and take their journey in the crypto world.
