I recommend this lecture. Knowledge that can be completed in just 1 hour!! I took the course right after seeing n8n and have no regrets. Thanks to it, I successfully created a personal report that lets me view multiple exchange accounts and DeFi wallets at once. And by integrating the CoinMarketCap API, each asset's price, market cap, and volatility updates in real-time, so the latest portfolio gets recalculated with just one button click, which is really great. Now I check balances from domestic/international services like Binance, Flipster, Upbitthumb and wallet-specific returns on an integrated dashboard, and set up rebalancing workflows to run immediately when needed, definitely saving 2-3 hours a day. Even when I'm outside, I can open the dashboard on mobile to check volatility alerts and automated trading results, which puts my mind at ease. Thanks to this, I have more free time. For those like me who spend a lot of personal time on investing, I highly recommend this for saving time.
