GainBitcoin became a major alleged cryptocurrency fraud in India by combining Bitcoin’s early popularity with an extraordinary promise: fixed returns from cryptocurrency mining. Launched through Variabletech Pte. Ltd., the scheme allegedly offered investors a 10% monthly Bitcoin return for 18 months, promising 1.8 BTC for every Bitcoin invested.
Bitcoin Mining Became the Sales Pitch
According to court records, investors were told their Bitcoin would fund cloud-mining operations. The model spread through multi-level marketing, with participants receiving incentives for recruiting others.
Early payouts strengthened confidence, encouraging participants across the country to reinvest. The supplied account describes tens of thousands of investors and Bitcoin worth thousands of crores entering the network.
However, a guaranteed monthly return was a warning sign. Bitcoin mining profitability depends on variables such as prices, electricity costs and mining difficulty, making consistent returns difficult to guarantee.
MCAP Tokens Replaced Bitcoin Payouts
As the scheme came under strain, investors reportedly faced withdrawal delays and changing payout conditions. Bitcoin payments were eventually replaced with MCAP tokens, reducing the need to source BTC while leaving investors exposed to a less liquid asset.
The CBI says Darwin Labs helped develop MCAP and its ERC-20 smart contract, alongside GainBitcoin’s technology infrastructure, including GBMiners.com, a Bitcoin payment gateway, Coin Bank wallet and the investor-facing website.
Investigation Continues in 2026
GainBitcoin remains an active enforcement case. According to the CBI, the Supreme Court directed it in December 2023 to investigate related FIRs as a common agency.
In March 2026, the CBI arrested Darwin Labs co-founder and CTO Ayush Varshney after immigration authorities intercepted him in Mumbai.
The case’s estimated scale varies. A 2026 investor petition before the Supreme Court alleged that more than one lakh investors were affected and over two lakh Bitcoins were siphoned off. Those figures remain allegations rather than a final judicial finding.
Final Thoughts
The GainBitcoin case illustrates how cryptocurrency, referral marketing and guaranteed-return promises can be used in an alleged Ponzi scheme. Its central lesson remains simple: investors should question where returns originate, whether revenue can be independently verified and whether payouts depend on continuous recruitment.
