Our take
Coinigy
Coinigy functions as an operational bridge for traders managing balances across multiple cryptocurrency venues. By aggregating exchange APIs into a single workspace, it eliminates the friction of switching between fragmented browser tabs to monitor market movements or track combined net worth. The platform leverages TradingView charts, equipping users with extensive technical indicators, drawing tools, and historical candle data across hundreds of spot and derivative pairs.
For cost-conscious evaluators, the primary question centers on whether paying a recurring subscription fee delivers sufficient operational efficiency over free native exchange interfaces. Coinigy does not act as a broker or custody your assets, meaning underlying exchange execution costs and network fees remain separate. Traders who actively trade across several accounts often appreciate the unified terminal and alert engine, provided their volume and strategy justify the monthly software overhead.

Relai positions itself as an accessible gateway for European residents seeking straightforward Bitcoin exposure with genuine self-custody from day one. The mobile platform bypasses traditional custodial holding balances, settling all completed purchases directly to private seed phrases generated on user devices. This architectural choice removes central counterparty custody risk while maintaining approachable workflows for scheduled dollar-cost averaging orders.
The service structure makes deliberate compromises. The platform focuses exclusively on Bitcoin, ignoring broader multi-asset ecosystems and smart contract protocols. Base transaction costs remain higher than wholesale order-book exchanges, though fee reductions apply to larger volumes and recurring plans. For cost-conscious savers who prioritize direct key ownership over complex trading tools, Relai provides a clear and focused entry path.
