New on FinoLib · Volume II: Capital Markets
I have added a new article to FinoLib, my finance education website: Cryptocurrency History: Money, Bitcoin and Real Fintech (UPI, ONDC), part of Volume II: Capital Markets. This page gives you the core of the topic in expert but plain language; the full article goes much deeper.
11.7 Where Crypto Fits in Monetary History
The idea in plain words
Some people see crypto as a digital successor to gold. But it has gained ground mainly where regulated wrappers provide stability and access: spot ETFs, tokenized Treasury funds and reserve-backed stablecoins. FTX showed that the decisive risk is custody without segregation, meaning customer assets mixed with the firm’s own, not the technology itself.
Key points
■The SEC approved spot bitcoin ETPs on January 10, 2024, and generic listing standards on September 17, 2025.
■Tokenized Treasury funds held about $14.8 billion on October 4, 2026.
■FTX customers receive about 119% of claims fixed at November 2022 prices: 1 BTC returned about $20,076.
A closer look
Returning to Volume I’s Part 0 monetary history arc — barter, commodity money, metal coins, paper receipts, the gold standard, Bretton Woods, fiat currency — cryptocurrency’s proponents frame it as the next logical step: a return to a hard-capped, scarce monetary asset (echoing gold) but in digital, globally transferable form, free from any single government’s discretionary control. Skeptics counter that money’s core historical function has always been stability and near-universal usability for everyday transactions — exactly the two properties Bitcoin’s price volatility has, so far, most conspicuously failed to deliver at scale, which is precisely why stablecoins, not volatile cryptocurrencies themselves, have become crypto’s most widely adopted practical payment use case to date.
Decision rule
A reading rule for any crypto holding: ask whose balance sheet it sits on before asking what the token does. If an intermediary holds it, confirm three things: client assets are segregated and reconciled daily, the terms leave title with you, and your claim in insolvency is to the asset itself rather than to its dollar value on the filing date. If any answer is unknown, treat the balance as an unsecured loan to the platform and size it accordingly.
The costliest mistake
Leaving coins on an exchange that does not segregate them. An FTX customer with 1 BTC was “repaid in full” at about 119% of a $16,871 claim, about $20,076, when the coin itself was worth $63,000: a shortfall of $63,000 − $20,076 = $42,924, or about 68% of the coin’s value at the time. Hold long-term positions in self-custody or through a segregated, regulated wrapper, and keep on any exchange only what you are trading.
11.8 Real Fintech: UPI, Account Aggregators, ONDC, BNPL, Embedded Finance and Neobanks
The idea in plain words
Most of fintech is payments economics. On cards, a fee paid by merchants, called interchange, funds rewards, credit and chargebacks. Bank-to-bank systems such as ACH, FedNow, RTP and India’s UPI move money for cents or nothing. Buy-now-pay-later and neobanks earn from merchant fees and interchange. Embedded finance, where financial services sit inside other apps, is only as safe as the ledger behind it.
Key points
■On a $100 card sale at 2.9% + $0.30, the issuer gets $2.60, the network about $0.16 and the processor $0.44.
■Regulation II caps large-issuer debit interchange at $0.21 + 0.05% + $0.01; exempt issuers averaged 2.2 times as much in 2024.
■BNPL earned 4.02% of sales against 3.01% costs in 2021 (CFPB).
A closer look
Most fintech is a contest over who earns the fees on payments. On a card payment the merchant pays a merchant discount rate (MDR); most goes to the cardholder’s bank as interchange, a slice to the network, the rest to the merchant’s processor. Each firm’s share is its take rate. A $100 online purchase on a Visa Signature Preferred card (interchange 2.50% + $0.10) through a processor charging a flat 2.9% + $0.30:
Decision rule
Merchants: divide total processing fees by card sales and compare with the interchange your card mix implies; if the gap exceeds about 0.5 point on over $1 million of card sales, or much of your volume is regulated debit, ask for interchange-plus pricing (a heuristic). Use ACH or an instant rail for large payments that need no chargeback. Anyone keeping money in a fintech app: confirm the partner bank by name and that your balance is recorded in your name there; treat any balance you cannot verify as uninsured.
The costliest mistake
Assuming a fintech balance is an insured deposit. FDIC insurance pays when an insured bank fails; it does not rebuild a non-bank’s ledger. Synapse’s users faced a $65–95 million shortfall, and the CFPB’s later $46.2 million allocation from its penalty fund covered less than that gap.
