Everybody has their own opinion and surely some of them want to express it. This guy does not trust bitcoin and I respect his idea. However, It is clear that he does not spend much of his time to make research deeply on bitcoin and he is a conservative who put too much faith in gold. So don't let this guy tell you what to do. Having your own opinion is important. Don't invest in bitcoin if you dont own a perspicacious mind.
Personally, bitcoin can become digital gold but gold will not be replaced by bitcoin. Both of them will become important pieces of the financial. Together, they create a much more attractive market for us to jump on and take some money.
Sometimes lack of knowledge or ignorance, is the reason why people are hesitant to see what is in front of their eyes.
But if he will be open-minded and check the facts behind what he is talking about, maybe he will change his outlook in life.
We don't need other's opinion, just to change our perspectives towards a specific subject.
It is our duty, to educate ourself, so as not to be deceived by insights from self-proclaimed experts or known personalities.
Everyone can say something on basically anything. But at the end of the day, it is you, alone, who is responsible to take care of your own portfolio.
