I don't see anything dangerous in crypto industry, we just need to be vigilant and careful of those we making deals with during ico and we must be very careful of hackers
It is not dangerous because cryptocurrency wont kill us . It is only risky once we invest our money. Yet we dont't have to be afraid of to take a risk as we make our own research about cryptocurrency that we can see how great it is and the potential to earn a lot once we invest on it. If you decide to invest in cryptocurrency either money ,time or effort you only have to believe and do your part.
