Hey guys now that the bull market's officially over I just wanted to extend a wholehearted thank you to everyone. I'll be deleting my telegram account and logging off. Sold everything last night and waited about 12 hours to post this - had to hold some space for myself to process everything. You guys are like brothers to me and I'm so glad that we all finally made it together this cycle. Already called my real estate agent and I've secured a plot of land in the mountains. Fully off the grid from here on. I'll miss you all but I'll always remember our time in the trenches together.

This website is amazing! I wish it gets the same popularity as L2Beat. Actually, it could easily be larger, as wallets are much more interesting for users than L2s.

I believe lack of privacy NOW is a strategy for the privacy in the LONG TERM. We scale, get more users by being a casino with low fees. On the next bull market we will attract also non-gamblers by offering privacy on L2s like @aztecnetwork
