I have heard this before, mostly around the time of Brexit and also a little bit before during the stable price and I have also heard it now here.
I think it is pretty awesome that the media is starting to publish more positive news about bitcoin alongside all the negativity they publish about it. and it will help bitcoin a lot.
but as for bitcoin instead of traditional investment, I don't agree with it.
although bitcoin is an excellent investment and it has been for about two (1.5) years but it is always a better idea to diversify and change the amount of investment in different markets depending on their profit potential and also the risk that particular market has.
and this potential and risk in bitcoin market is high!
