Market Trends & Security Concerns - Sandwich attacks on Ethereum cost users nearly $40 million in 2025 [1] - Despite DEX volumes surging from $65 billion to over $100 billion monthly, sandwich attack extraction sharply declined [1] - Monthly sandwich extraction decreased from approximately $10 million in late 2024 to $25 million by October 2025 [1] Attack Characteristics - Attack frequency remained high, ranging from 60,000 to 90,000 per month [1] - 38% of attacks targeted low-volatility pools, including stablecoins and wrapped assets [2] - 12% of attacks impacted stable swaps, where slippage is unexpected and particularly damaging [2] Profitability & Attacker Behavior - Average profit per sandwich attack is only $3 [2] - Only six attackers generated over $10,000 in total profit during 2025 [2] Potential Mitigation - The decline in sandwich extraction may indicate increased adoption of MEV-protection tools among traders [2]

Centralized Exchanges (CEXs) vs Decentralized Exchanges (DEXs) - CEXs act as intermediaries, providing a user-friendly interface and handling fiat deposits/withdrawals, making them suitable for new crypto buyers [3][11] - CEXs offer automated trading tools and tax documentation, simplifying the trading process and tax reporting [13][15][16] - CEXs face challenges including high fees (01%-05% per trade, 05%-1% spread), strict KYC requirements, limited asset selection, and risks of hacks, outages, and potential collapse [17][18][19][21][22][28] - Industry experts note that even major CEXs are advocating for self-custody, highlighting the inherent risks of leaving assets on exchanges [29] Decentralized Exchanges (DEXs) - DEXs offer direct crypto trading from user-controlled wallets, providing access to a wider range of assets, lower fees (eeg, Edex charges under 004%), and self-custody, eliminating counterparty risk [6][8][34][37] - DEXs require users to have existing crypto and technical knowledge, and mistakes are irreversible, creating a barrier for new users [30][31][32] - DEXs can experience lower liquidity and front-running bots, potentially impacting trade execution and pricing [33] - Early DEX users may benefit from airdrops, offering potential rewards for platform adoption [39] Strategic Usage - The industry suggests a combined approach: using CEXs for fiat on/off-ramps and DEXs for trading, holding, and exploring new assets [41][49] - OKX is highlighted for its fast fiat withdrawals in the UAE (under 5 minutes) and Europe (within hours) [14][41][42] - Edex is favored for its user-friendly interface, liquidity aggregation, and cross-chain support [50][51][52] - Coin Bureau team secured deals for viewers, including discounts on trading fees and multiplier on points [43][53][54]
