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. Experienced people and beginners love to play. Therefore, growth points can be in expanding people's awareness and offering new tools.
You do not have to think about how to sustain bitcoin growth, bitcoin is decentralized and not for a single person, the world is adopting it and it is known all over the world already. Just like gold and other decentralized asset, we like it or not, bitcoin will increase in price and value.
I think it's time to make websites with prices in different currencies: dollars, euros and crypto. It seems to me that this will contribute to the popularization of cryptocurrencies. Strengthening the popularity of cryptocurrencies would lead to an increase in their rate, to more lively trading, and as a result, to strengthening the status of cryptocurrencies.
There are over 400 crypto exchanges that are centralized, there are still other types of exchanges, they are all websites. All these have happened in the past. It is just like you reverting situations back to the past when all these have not been created like many years ago. I see this your post not to necessary.
