It's just as simple as the both goes hand in hand both for technical and fundamental analyst. Trading is one career that requires steady update on how the news could affect the direction of a trade or possibly how an indicator or a candle stick can direct a trader on where the market is heading. If there is no time for a consistent update on your previous knowledge as a trader I guess at some point some level of gambling sets in.
1. If you are full time trader yes. But full time traders in stocks and shares, where you handle commissions and budgets and portfolios.
2. Why I say not for crypto? Because news does not affect it like stocks do. The highs and lows of crypto markets seem to be affected by events more than news (like whales selling, regulations banning stuff). News like central banks decisions and financial crashes do not seem to hit crypto until after a while.
