there is still a lot to be done for the security of the developers of crypto-exchanges.
security of most exchanges are already solid . hackers are just smart people because they can find a way to bypass the security of any system that they like to hack
This report shows us all how much the cryptoculture in the world is just beginning to develop.
do you mean hacking is a indication that a thing is just developing ? crypto is already fully develop imo because it is been already 10 years ever since it was born .
Does it includes all the scam exchanges, for example when cryptsy got ''hacked'' ?
no its not . 1billion dollar worth of bitcoin is kinda small compared to the overall total market cap of bitcoin .
