This can ben seen like an advice, so I don't see as wrong. We can lose all our investment in cryptocurrencies, and it doesn't require to see a bitcoin reaching 0 for that 
Investing in cryptos is a risky game that some people sometimes forget. Everyone must consider investing only what they can afford to lose, this is said everywhere on this forum but it's still the best advice, because yes, you can invest in something which will worth near 0 later.
About the graph showing price volatibility in the news, well, this is not surprising to see cryptocurrencies with an higher rate, haha. What do they expect ? Thet compare gold and cryptocurrencies, but this is not comparable. More the market cap is high, the less volatility will be, because with an higher market cap, you'll need much more money to shake the market. But this doesn't protect you against crashes.
