Already at the end of 2016, they were more than 10 million, while 20 million was exceeded the following year, at the end of 2017, probably thanks to the speculative bubble.
At the end of 2018 it was also exceeded 30 million, and then it took six months to get to 40, in June 2019. Blockchain.com itself reveals that on the 25th of September the total number of wallets exceeded 42 million. The increase is therefore not linear but is accelerating.
The report does not take into account bitcoin wallets in general, but only those created on the Blockchain.com platform, which allows you to keep other cryptocurrencies. Moreover, it does not refer to the number of public addresses but to the number of wallets. In fact, each wallet can also contain several addresses.
For example, as far as bitcoin is concerned, there are now almost twenty million addresses that contain BTC for a value equal to or greater than one dollar, while the number of active addresses in the 24 hours is more or less stable around 700,000.
Therefore, the Statist report reveals that the Blockchain wallets that have been created are many more than the individual bitcoin addresses that contain BTC for a counter value of at least one dollar, revealing that probably many wallets have been created but are still empty, or contain very few tokens, or contain no Bitcoin but other cryptocurrencies.
In addition, the number of active addresses is much more limited than the number of wallets that have Bitcoin, so many of them are very little active.
Some conclusions can be drawn from this data.
First of all, the cryptocurrency wallets that have been opened are certainly much more than 40 million, since these are only those opened on the platform Blockchain.com. Therefore it is conceivable that many tens of millions of people in the world have opened their cryptocurrency wallet.
Secondly, most of these do not contain Bitcoin or contain so few that they are negligible. Finally, the number of wallets is growing rapidly, especially after 2017, and particularly in 2019.
