But most of the time, people put the year where they first launched the site, and bitlucy is launched only this year. Anyway, royse can give us more clarification on this matter.
It's not really necessary whether to follow the launch date or the idea date, it will still be valid nonetheless. We might not know whether they already tested it in a local IP since 2019 and just registered 2021 OR launched with another domain from 2019 and just registered a commercial one on 2021.
Welcome, Bitlucy! I see your team even Royse are so engaging towards the community with an active 24/7 support. I'm looking forward on more engagements and hopefully be a casual player on your website! Good luck on your journey! Still have so many things to improve at tho.
