It sounds like a strategy to lose all your money  buying tokens randomly is definitely a bad idea. But I agree with you in that charts, indicators and a lot of alpha are usually bs and don't have anything based in reality backing them up. People will point to a chart and claim whatever the chart shows is guarantees that it will go up, that's nonsense. At the end of the day nothing is better than doing your own due diligence, educate yourself so you can make the right decision instead of trusting these influencers trying to scam you.
