There is people who only come to bitcoin investment with the mindset to instantly double their money within the period of change in bitcoin without knowing what the price of bitcoin could turned out to be within next moment. So before discussing with anyone about bitcoin or to invest in bitcoin carefully pass the knowledge about the volatility level before they could finally take their decisions to investment in bitcoin or any other cryptocurrency because whatever that happens to the person's fund you could held responsible for misleading them to invest in cryptocurrency that leads to their lost.
No doubt, some people don't want to think of the risk involved in investment rather, they are being carried away with positive testimonies.
It is something common with most bitcoiners especially when it comes to referring people to Crypto, they wouldn't spend much time to explain the risk associated rather, they'll only tell how their investment was successful....
This is common on social media.
I guess to the newbies, it is very much preferred to DYOR after being persuaded to invest in any Cryptocurrency before putting money into it.
