Crypto Payment Landscape - Crypto payment solutions have largely been considered unsuccessful since Bitcoin's inception [1] - EtherFi Card data indicates most transactions are small payments, ranging from $1 to $50 USD [1] - Onchain transactions, regardless of origin (crypto wallet or card swipe), settle on ETH L2s, Solana, etc, with gas fees [1] Challenges and Opportunities - Visa and Mastercard take a significant cut, but this may be a temporary situation [2] - New non-custodial crypto cards are developing their own payment rails, exemplified by Payy [2] - Crypto cards initially leverage Visa and Mastercard's reach [2] - Stronger rewards, such as cashbacks, collateral-backed credit, and yield, attract users [2] - Growth beyond the crypto niche could allow these networks to encroach on the legacy payment system [2] Future Prospects - Blockchain technology is already facilitating spending and driving stablecoin adoption [3] - The industry anticipates self-custody options and DeFi integration through EtherFi Cash in 2025 [3] - Users will no longer need to convert stablecoins to fiat currency [3]
