Bitcoin is not an investment, it is a hedge.
Bitcoin is not vulnerable, it is the safest technology on the face of the earth.
Bitcoin is not uncertain, it is an evolution of money as we know it.
I think that for you and your friends what is missing is fundamentalist study. Because from what you wrote your knowledge about bitcoin is none.
You're actually far from the truth I must tell, you saying shit. However you may retwist it; Bitcoin is uncertain, Bitcoin is vulnerable, Bitcoin is volatile, Bitcoin is an investment. Use your head and forget what others say about the market cos these are the core attributes of Bitcoin and cryptocurrency in general. Copy and paste ain't gonna expand your scope about the market. My friends are right cos I talk out of sophistication. I have alot to unveil, yet you ain't here to learn from a dumbass like me. Aloha 🕊️
