With the rate of attacks on cyber because of cryptocurrency, I expected that there will be a more strict security and this will lead to more generation of cyber security firm which we actually need, at least with these dedicated team of security too, scammer will really find it hard to always have their way in the dark market.

If they are really active, honestly they could make very big differences in the market today.  The blockchain sector is still growing and we should expect a boom in it in near future, so it is better they prepare for the unthinkable now, because as we develop more, the cybercrime rate regarding cryptocurrency will also increase, so we cannot allow the crimes in cryptocurrency to be more popular than the core reason for its creation.
