Hey guys, thank you for your comments It's my first time writing a post at bitcoin talk, but it's not a paid post.
Looking at their Twitter profile, the service is operated by BlockCrafters (the company is based in Seoul), and assets are managed by Block Crafters Capital that is blockchain VC based in Singapore. https://cryptofundresearch.com/block-crafters-capital-fund-info/

I will drop their SNS accounts so you can evaluate them too.

The maximum deposit amount is 30 BTC, and the minimum deposit amount is 0.0001 BTC for a 1-month deposit.
I can provide screenshots of the evidence that I'm using the service if anyone teaches me how I can add images in the post ..
