Why Choose a Bitcoin-Only Investment Platform?
The shift toward Bitcoin-only onramps reflects growing awareness that not all cryptocurrencies are created equal. While altcoin exchanges rose during speculative booms, many collapsed after events like the FTX implosion. In contrast, focused platforms have proven more resilient.
Key advantages of going Bitcoin-only:
- Lower fees: Streamlined operations reduce overhead.
- Greater security: Engineers can optimize defenses around a single blockchain.
- Regulatory clarity: Bitcoin is increasingly recognized as a legitimate asset class.
- Deeper expertise: Teams become true specialists in Bitcoin infrastructure.
- Aligned incentives: Companies succeed only if Bitcoin succeeds.

Why Automate Your Bitcoin Purchases?
Automated recurring buys—also known as dollar-cost averaging (DCA)—are widely regarded as the most effective strategy for accumulating Bitcoin over time.
Key Benefits of Recurring Buys

- Reduces emotional decision-making – Avoid FOMO and panic selling.
- Low time preference – Focuses on long-term growth over quick wins.
- Tax-efficient – Minimizes frequent trading and associated reporting.
- Accessible to all budgets – Start with as little as $5 per week.
- "Set it and forget it" simplicity – Builds wealth passively.
Platforms like Swan and Amber make automation seamless, allowing users to grow their stack without constant monitoring.
