About
Cryptocurrency — digital currencies using cryptographic proof instead of institutional trust for transactions — promised to replace banks, create financial inclusion for the unbanked, eliminate corruption, and disintermediate every financial system. Since Bitcoin's 2009 launch, the industry has produced $3 trillion in peak market capitalization, spectacular fraud, genuine innovation in specific use cases, and a lengthy debate about what problem it actually solves better than existing systems.
The genuine use cases: Bitcoin as a store of value (digital gold, limited supply 21M coins, inflation hedge in countries with currency instability — El Salvador, Argentina, Nigeria show strong adoption); cross-border remittance (cheaper for some corridors than traditional wire transfers); smart contracts for specific applications (insurance, supply chain verification, decentralized finance for the unbanked); and NFTs for digital ownership proof. The failures and scams: FTX ($32B exchange to bankruptcy in 72 hours, SBF fraud); Terraform/Luna ($40B collapse); Mt. Gox (850,000 Bitcoin lost in 2014); BitConnect (Ponzi scheme, $4B); OneCoin ($15B fraud, Ruja Ignatova still at large). Environmental cost: Bitcoin mining uses 150 TWh/year (equal to Argentina). The DeFi (decentralized finance) sector has had $6B+ stolen in hacks since 2020.

Fascinating Facts
- ◆El Salvador became the first country to adopt Bitcoin as legal tender (September 2021) — President Bukele distributed $30 in Bitcoin to every citizen — yet 2 years later, less than 2% of businesses use it for transactions, and the government has had to quietly walk back most of the implementation while still holding Bitcoin on its balance sheet
- ◆The OneCoin cryptocurrency fraud ($15 billion, 2014-2017) was run by Ruja Ignatova ('Cryptoqueen') — she sold tokens for a cryptocurrency that did not have a functional blockchain, raised $15 billion from millions of people globally, then disappeared in 2017 and remains on Europol's most wanted list despite the largest financial fraud manhunt in history
- ◆The $69 million sale of Beeple's NFT 'Everydays: The First 5000 Days' at Christie's (March 2021) marked the peak of NFT mania — within 18 months, 95% of NFT collections were worth essentially zero and the market had collapsed by over 90%, while the buyer (Metakovan/Vignesh Sundaresan) held an asset worth approximately $5-10 million
