7-in-7 #1: Launch issue — the seven things that matter this week

7-in-7 Digest issue dated 2026-10-01: Why this digest exists; Bitcoin ETFs are the new default allocation; Layer-2 fees stay under a cent; Stablecoins are the real product-market fit.

1. Why this digest exists

Seven stories, seven minutes, every week. No price predictions, no sponsored shilling disguised as news. Each item ends with the one action worth taking.

2. Bitcoin ETFs are the new default allocation

Spot ETFs now hold a meaningful share of circulating supply. Action: if you hold BTC in a retirement account via an ETF, you still need self-custody for coins you want to actually use (Step 4).

3. Layer-2 fees stay under a cent

Base and Arbitrum continue to process the bulk of Ethereum activity for fractions of a cent since blob space arrived. Action: stop paying L1 gas for small transactions — our Top 7 Layer-2s shows where to go.

4. Stablecoins are the real product-market fit

Stablecoin settlement volume rivals major card networks. Action: learn how USDC on Base or Solana works before your bank starts offering it.

5. Exchange proof-of-reserves is now table stakes

Monthly PoR has gone from novelty to minimum requirement after 2022. Action: if your exchange doesn't publish reserves, that is your sign — Top 7 Exchanges lists those that do.

6. Tax season never ends

Agencies are receiving exchange data directly. Action: connect a tax tool now (Top 7 Tax Tools) so filing is a click, not a reconstruction.

7. The quiz contest is live

Score 7/7 on the Crypto Basics Quiz and enter the launch contest for a share of $700. Action: /tools/quiz/ then /contests/.
