When I first started with cryptocurrency trading, I focused on doing a lot of research about different coins. I looked at their market caps, use cases, and the teams behind them. I also used tools like CoinMarketCap and TradingView for market trends and chart analysis. As for platforms, I found Coinbase and Binance user-friendly for beginners. A tip is to start small and diversify your investments to spread risk. What kind of cryptocurrencies are you looking to start with?
