Top 10 CoinGecko — Top Cryptocurrencies — March 18, 2026

March 18, 2026, saw the crypto market take a broad hit, with most top coins shedding value in the last 24 hours. Bitcoin held above $71,000 even as Ethereum slipped below $2,200, but the real story is Tether clinging to its $1 peg while Dogecoin plunged over 5% in a day—proof that meme coins remain the most volatile corner of the market. The surprise entry? Figure Heloc, a tokenized home equity loan product, cracked the top 10 at $1.03, signaling growing investor appetite for real-world asset tokenization even amid a downturn. XRP and Solana both dropped over 4% daily, yet their weekly gains show they can still rally when sentiment shifts. This list measures circulating supply times price, so it favors established giants and stablecoins—but Figure Heloc's presence breaks that pattern. CoinGecko pulls data from thousands of exchanges, weighting by liquidity to avoid manipulation, which makes this snapshot of March 18, 2026, a reliable gauge of where institutional and retail money actually sits.
