Disclaimer: This is not financial advice. All examples use paper trading / testnet only. You can lose 100% of capital in crypto. Always do your own research. When I started exploring crypto automation, every tutorial pointed me to the same places: Cryptohopper, 3Commas, Coinrule. Sign up, connect your exchange via API key, pay $30-100/month, let the cloud run your bot. I followed that path. Then I stopped and asked a question nobody was asking: Why is my trading logic running on someone else's server? That question changed everything.
