Knowledge on btc

I have been a btcoiner for a while now but I have really problems to explain to people the technicalities of it and I'm often blocked when they throw in reasonings like BTC will cause a wider wealth disparity or btc instrinsically will drive more illegal activities or that it's harmful for the environment etc. Are there any videos or btc "influencers" you can recommend that I can watch in way to educate myself and be better at arguments against it?
