The increases in transaction volume and the emergence of new exchanges proves that more and more people understand what bitcoin is. Because when we understand something, we invest not only speculate.
There has been a lot of FUD and negative propaganda directed against Bitcoin for the past several months. Despite that, Bitcoin managed to survive and thrive. When the exchange rates fell from $20,000 in December 2017 to $3,000 by March 2019, a lot many of the mainstream analysts were quick to predict doom for Bitcoin. But they were proved wrong (just like what happened in 2015). The mainstream media still remains openly hostile to Bitcoin, but the recent price changes prove that their stance doesn't really matter.
The data from the global cryptocurrency exchanges also confirm that interest in Bitcoin remains strong. Most of the exchanges have witnessed close to 100% increase in the number of users during the past 12 months. And this data is likely to be accurate, as almost all the exchanges have made KYC mandatory. The basics remain strong for Bitcoin. The number of users are increasing and the transaction volume is rising. What we need now is more mainstream investors in the Bitcoin domain.
