On 10/06, I was a speaker at a cryptocurrency event in Curitiba, Brazil, aimed at crypto enthusiasts. The event focused on various blockchain networks, and I was representing Polkadot as an ambassador. I seized the opportunity to have 16 HydraDx T-shirts made for distribution among some of the participants. It was a relatively small event with about 50 attendees, but it brought together people from various blockchain networks with diverse interests. I believe it was a highly productive event, as around 10 individuals who attended later joined the HydraDxBrasil Telegram group. The Brazilian community around HydraDx is continuously growing.

At the last minute, I managed to secure a slot with the event organizers to also talk about HydraDx Brasil. I adapted a presentation that @lolmcshizz shared with me (from Polkadot Decoded) and spoke to the audience about omniPool, DCA, splitting, and upcoming developments in HydraDx. It was a great event.

The request for tips here is to cover the costs of the T-shirts that I gave away at the event.

16 T-shirts
Each T-shirt cost $7,60 USD.

16 * 7.60 = $121,60 USD
Delivery fee: $10 USD
Total: $131,60 USD

131.60 x 0,00441568 = 29802,88 HDX
Total: 29802,88 HDX

PS: Below are photos of some people who won the T-shirts.

I did not request tips for the time I spent preparing and scripting the presentation because it was a last-minute situation, and I didn't have the opportunity to inform the council members beforehand. However, if you feel that there is no problem, please let me know, and I can create a new tip request. I dedicated approximately 5 hours to fine-tune the presentation, create a script, and deliver the speech.
