Coinbase CEO Brian Armstrong Makes a Strong Case for Global Crypto Adoption. Here's What That Could Mean For Your Crypto Portfolio.

Stablecoins give everyone access to a low-inflation currency.

DeFi applications are pulling unbanked individuals away from conventional banks.

Tokenized stocks are expanding the total addressable market for U.S. equities.

Coinbase (NASDAQ: COIN) CEO Brian Armstrong recently claimed crypto "doesn't get enough credit for the financial access it's already unlocked for the world" in a post on X. Armstrong noted that stablecoins allowed "anyone, anywhere" to access a low-inflation currency and send it "24/7 for a fraction of a cent", that decentralized finance (DeFi) applications gave "anyone access to credit" and unbanked individuals access to financial services, and that tokenized stocks would expose four billion "unbrokered people" to the U.S. stock market.

Armstrong's bullish take isn't surprising, since Coinbase is one of the world's largest cryptocurrency exchanges . If you agree with Armstrong's perspective, then it might be a good time to review how those catalysts could boost your crypto portfolio's long-term returns.

Stablecoins can be deposited into third-party lending markets, automated market makers, and liquidity pools to earn higher yields than traditional dollar-based savings accounts. However, some of those platforms are much riskier than FDIC-backed banking accounts.
