In Q1 alone of 2019 there was $356m in theft of digital currencies from exchanges and scams while losses from fraud hit 851m. This number includes the QuadrigaX scam which accounts to about $134m in total losses.
What can we do to help stop these from happening and getting worse?
It's so hard do deal with it. There's a bunch of scams and thieves out there. I guess being decentralised comes with this problem. And I also think that it cause a lot to the price change of a currency. In the end, we are the ones who needs to be responsible for our own security. Being aware on everything before putting anything else. Maybe in the future we can have the righteous site and bring those scammers down. In order for us to help the others from being a victim, we have to share our experiences so that they can also be aware and prevent the worst case happening.
