Things you should learn about bitcoin is that BITCOIN, just like any other cryptocurrencies, is not scam. Think of it as a digital currency so how will it become a scam? Just for example you have US Dollars and you dont do something about it, it's just currrency and will remain a currency. But if you make projects that involves bitcoin or we say US Dollars and your purpose is to scam people well that does not change BITCOIN as a cryptocurrency. The scammer are the ones who makes fraudulent projects to earn BTC and not the BITCOIN itself.
I hope you get my point because everytime I tell my friends about bitcoin they always said it's scam. Haist people nowadays!
