The story summarized from this hashtag is:

On May 22, 2010, a programmer named Laszlo Hanyecz bought a pizza for 10,000 bitcoins, which is the first known transaction using Bitcoin to purchase a real product.

At that time, the value of Bitcoin was nearly negligible, but today this is considered the most expensive pizza in history!

The hashtag is used by Binance (and other platforms) to celebrate this day every year through events, competitions, giveaways, or special offers, and uses the hashtag 10213410300 to share and promote this event, integrating it with the community.

The message behind the hashtag:

-Reminder of Bitcoin's origin as a currency that is actually used

-Celebrating the evolution of crypto over the years

-Building community ties in a fun way

As May 22 approaches, it is very likely that Binance will run a campaign with this hashtag.
