ExchangePaco: The Shadow OTC Crypto Market Defying Regulation

ExchangePaco: The OTC crypto market operating outside regulated exchanges

While major exchanges require ID, biometric data, and proof of funds, a parallel cryptocurrency market has operated under the radar for years. Without KYC (Know Your Customer) requirements, no limits, and fees around 3%, peer-to-peer trading moves from fractional Bitcoin to Amazon gift cards and PlayStation codes. The uncomfortable question remains: how much real volume escapes the Spanish Tax Agency (Hacienda)?

A market that began with a 3 BTC listing

More than five years ago, an individual created a hub for cryptocurrency trading between investors. The goal was simple: avoid centralized platforms and their costs while gaining anonymity. What started with 0.1 Bitcoin offers in hand (in Madrid or Valencia) soon diversified. Ethereum, USDT, Monero, and even Pi Network appeared in listings. Not all assets are crypto: discounts of up to 20% on gift cards and subscriptions to PlayStation below retail price are also traded.

Risk as currency

Security is the Achilles' heel. Transactions occur in person at public locations or remotely via bank transfers, with no intermediary. Consequently, private trading groups have emerged that, according to warnings, charge up to $200 for entry and demand personal data. The use of smart contracts like Hodlhold has been proposed to guarantee exchanges, though adoption remains limited. "Meeting a stranger at 11:00 PM in a dark alley to swap crypto for cash is a joke," one participant joked.

The Tax Agency watches but does not intervene

The specter of the Tax Agency (Hacienda) looms over every transaction. Advertisers themselves mention "no KYC" and "tax avoidance" as hooks. However, the Spanish Tax Agency has improved its blockchain tracing capabilities. A recurring warning states: "Thread monitored by CNI-Tax Agency." The opacity of the OTC market complicates oversight, but bank transfers and on-chain movements leave traces. Those buying or selling outside official channels assume a fiscal risk that, for now, seems tolerated.

From Bitcoin to 'cholos': market fragmentation

The offering extends beyond conventional cryptocurrencies. Exotic tokens like "cholos" (88 million valued at €9,500) and coins from minor projects appear. Physical items, such as silver coins, are also traded. This diversity reflects a community seeking alternatives to traditional channels but also acts as a magnet for scams. Participants acknowledge that the system relies on fruta and word-of-mouth, a fragile model when amounts grow.

Can this market continue to grow without regulation? Judging by uninterrupted activity over years, the answer is yes. However, tax pressure and the sophistication of official exchanges could reduce its appeal. For now, digital barter among individuals survives, challenging both Binance and the Tax Agency.
