This is not correct. Bitcoin linked to criminal usage is reducing. Fiat are still more used than cryptocurrencies by criminals. Other cryptocurrencies,, especially stable coins like USDT has taken over bitcoin in criminal usage. I do not know what caused this. Maybe it is the high fee transaction and how stable coin has dollar pegged price are the reasons.
You probably didn't get the point. The post says that Bitcoin's popularity has made it a prime target for cybercriminals which means that criminals such as hackers and scammers target people who have bitcoins only to steal from them, it wasn't about criminals using Bitcoin for their criminal activities.
What I think about this is that hackers and criminals won't be able to reach your bitcoins or other assets if you don't allow them to do so. Most of us aren't very careful with our assets and wallets which is the reason why they get compromised, if we don't use our wallets openly and connect them everywhere or let people know where we hold our assets, they wouldn't get compromised and our assets will be safe.
It is not that difficult to safeguard our assets, we just need to be a bit careful and that's it.
