The European Central Bank (ECB) is soliciting questions from the general public on cryptocurrencies, among other topics, for its third Youth Dialogue.

In an announcement Thursday, the ECB invited Twitter and Facebook users to ask the bank’s president, Mario Draghi, questions about a possible global economic crisis, Europe’s economy, as well as cryptocurrencies and blockchain.

Notably, the ECB repeatedly listed some example questions about cryptocurrencies on its announcement page.

Similarly, in a tweet, the ECB highlighted bitcoin as a potential topic, specifically honing in on whether it could displace traditional, government-issued currencies.

Could #bitcoin offer a viable alternative to traditional currencies? Join in our third #ECBYouthDialogue and tell us what you think! If you have questions about #cryptocurrencies, why not #AskDraghi!

People interested in asking questions have until Jan. 23 to ask them using Twitter or Facebook. Draghi is set to respond to the questions in a series of videos next month on Feb. 12.

While the ECB is notably highlighting this topic area, Draghi himself has weighed in on the issue several times in the past, stating in November that they have a limited impact on the European economy.

Further, Draghi has said that he doesn’t believe cryptocurrencies are mature enough to regulate.
