Welcome to this forum Thunderpick.com. I hope you enjoy staying here and can communicate with many members and share your website. Giving out bonuses for new members can invite many gamblers to your site, especially when you can actively manage your thread and share the site's updates or events. I am trying to register to see what is inside and I found that with many gambling games available on your site, gamblers stay for a long time and have fun playing every gambling game. I am trying to deposit on a minimal amount, maybe equal to $4.50 but it needs to wait to let it get confirmed and see it later at my account.
There are various bonuses we're currently giving to players as a part of mentioned before Thunderpick Bitcoin Series. There is a "Bet €50 & Get €50" welcome offer, Free Bet codes posted regularly (and hidden!) on our social media's or €5000 Giveaway on Gleam (https://gleam.io/gMsfN/massive-5000-giveaway-thunderpick-bitcoin-series). Make sure to check out our Twitter, Discord, Instagram or Blog to enjoy them all 
I think you can also announce your update in social media to this forum so we can know directly from you. About the Free Bet codes, I think you can make separate codes for Thunderpick.com social media and in here so you can see where the people come from by using different Free Bet codes.
