I asked some of my friends watch a YouTube video on bitcoin recently. Everything is technical for the ⅓ of the video, but things quickly went downhill afterwards. It talked about MtGox and Silk Road, giving them a impression that Bitcoin is a scam of pyramid scheme, you don't earn sustainably and bankrupt eventually. Since then, they went away , not listening any word starting with crypto-.  Anyway to save this situation?

Hi everyone,
Cryptocurrencies are booming, and is a good idea to get into it now. A friend of mine watched a documentary about Bitcoin and saw the negative news. Afterwards, he is completely stuck and will not trust in any online payments, especially any cryptocurrencies. What do I need to do to get him back to normal again? Anyone have positive news about Bitcoin that I can let him know?
Thanks
