That's a always a concern mate, especially since the market and all its transactions are heavily inclined with the use of the internet. Thus, we can't stay away from the fact that many shady personalities will take advantage of the how they can profit from the market, unfortunately, in the expense of other people who are working. And I would say yes that they can really chance the landscape of the market, especially if a "hack" would affect a big part of the market.
I agree. Hackers are everyone's concern. These bad people trying to steal our accounts and our money. It is really our responsibility to keep our accounts safe from these hackers. We should be very careful about it to avoid being hacked because these people are everywhere.
The security measures are there for everyone, and it is important to always make use of them, and it would be utter carelessness for anyone who still at this age does not know how to keep their accounts secured.
