Making Bitcoin once again popular is actually very simple. Just need its price to rise, so there are many potential investors who are now waiting to buy it. People don't dare to buy bitcoin now because they are intimidated by the huge drop in bitcoin, but that doesn't mean Bitcoin loses its value.
it's not enough just to the price goes up but all countries in the world must accept Bitcoin as a digital world asset, to be more popular again in my opinion Bitcoin always gets positive news or is widely known by the entire community. people are now waiting for the decline of Bitcoin until the lowest price, then they will buy Bitcoin and save it for the long term time.
