Oscar Costa Revienta Cerebros, operating from Granada, Spain, is the central figure behind Bitwabi, a cryptocurrency-based multilevel marketing venture. The company promises investors annual returns as high as 400% on bitcoin investments.

Before Bitwabi, Costa managed a pet kennel and animal shelter. Later, he promoted the ArbiStar Ponzi scheme. Evidence of his ArbiStar involvement has since been largely removed from the internet.

Bitwabi offers no retail products or services. The company's entire business model relies on affiliates recruiting new members who then invest funds. Affiliates market Bitwabi membership itself.

The compensation structure for Bitwabi affiliates involves investing funds in exchange for promised monthly returns. Investment tiers range from Bronze at €250 EUR, promising €83 EUR monthly for a year, to Premium Plus at €12,000 EUR, with a €4000 EUR monthly payout over 12 months. These advertised returns represent an annual yield of approximately 400% for the highest tier.

Referral commissions are distributed through a unilevel compensation plan, capped at ten payable levels. Personally recruited affiliates form level 1, receiving a 30% commission on their investment. Affiliates recruited by those on level 1 become level 2, and so on, down to level 10. Commissions for levels 2 through 10 are set at 2%. To access commissions from levels 6 to 10, an affiliate must recruit a downline whose collective investments reach €50,000 EUR.

A Leadership Bonus is awarded when an affiliate's personally recruited downline invests €150,000 EUR. This bonus is €15,000 EUR paid in bitcoin. The initial qualification for this bonus also earns the affiliate a 15-day trip for two to the Dominican Republic. The bonus can be qualified for repeatedly.

Affiliates achieve VIP status, designated as Global Bonus earners, under specific conditions. They must qualify for residual commissions across all ten unilevel team levels, earn the Leadership Bonus twice, and generate €5 million EUR in investment volume within their first ten unilevel team levels.
