I recently stumbled across a site called Richmond Berks
https://richmondberks.com/?ref=rbd210102 (Yes it's my referral link...who cares) and it seems worthwhile so far. It let's you stack up RBB (a bonus currency in Richmond Berks Ltd. Company) by a small percentage rate and It pays out in BTC and USD. One RBB equals $1 (USD) and I've earned 111.00 so far. There are loads of videos with payment proofs from withdraws all over youtube.
At first I thought it might another ponzi scheme but, so-far-so-good. I'm actually digging it and customer service responds quick-like through support chat. The companies email and phone are real (I called and emailed with answer/response) and clearly visible on the home page. They also showcase there business license, certificates, partner contracts and legalities.
I haven't invested yet, however they offer a money back guarantee. Think I'll start out with a few satoshi to start.
Just thought I'd share.
