For someone totally new to this cryptocurrency space, I will say it is very bad idea or advice as you say to look into Altcoins. OP is looking at getting into bitcoin for investment purposes there is currently no altcoin that stands out as an investment asset.
That's make sense.
As for resources to read, OP doesn’t need TradingView which is a tool or platform for drawing Charts, it is mostly used by traders which OP currently isn’t and shouldn’t consider going into (at least at the moment)
You got it wrong. Tradingview has
crypto news section which is they collected from trust news website about crypto. It isn't just drawing and that's why i recommend to op to watch the news instead doing technical analysis.
