It seems like your English isn't good enough to make a judgment about what he's said, because your assessment of his suggestions is completely false and out of context.
I hope you are right.
Anyway my intent is not to discredit the cryptocurrencies or people who create them.
I'm very pro-crypto.
I just worry because the gov used to publish fake news against crypto, spread terror messages about risk, volatility, blah blah just because crypto can hinder their business.
And now i see a crypto VIP suggesting to invest in traditional assets... it makes me worry and think the gov is threatening them (they did that to Assange , Snowden, etc., so it's not fantasy )
There has been, and there will be more, fake news from governments and central banks. So that's a plausible thing to worry about. Just a few days ago the Polish Central Bank has been caught paying off a Youtuber to spread FUD against crypto.
But Vitalik is not in that boat, at least not right now.
I'm personally not very worried about any of the FUD though. It seems like the establishment is already aware of the fact that they can not possibly stop Bitcoin & co. So the worst thing that I could see happening would be FUD campaigns to push down the price so that the establishment can buy large amounts of crypto for very cheap before allowing it to skyrocket. That's their usual game. Keep in mind that the MSM are their puppets.
Also, I personally invest in traditional assets as well. You should always diversify in a way that would ensure that if the worst scenario took place you would still be ok with the outcome. Imagine you had everything in crypto, and crypto goes up to a multi-trillion dollar market cap, but you somehow lost access to your coins. What now? If you sold some of your profits for fiat, gold, stocks, or whatever else you would still have something.
