Give me a quick answer to these  3 questions without looking it up:

How long is a billion seconds?

How long is a trillion seconds?

I’m writing to share my happiness with you.

This is my first Halving I’ll enjoy as a Bitcoiner! During the last halving I was just studying Bitcoin and now…. I finally managed to publish the 21 Lessons by nostr:npub1dergggklka99wwrs92yz8wdjs952h2ux2ha2ed598ngwu9w7a6fsh9xzpc in Greek!

It will be shown for the first time during the Greek Halving Party we’ve organized at Santorini island. Very glad I’m in the organising team and contributed to the event too.

Cheers!
