I'm generally curious what everyone's thoughts are on this. Say, for instance, you find a flaw / bug / exploit in a cryptocurrency. Instead of notifying the developers and / or modifying the code yourself, you think "Hey, I could profit from this!".
Depends on which type of coin it is.
If it's like Monero with a toxic userbase that's attacking all the others and being just too arrogant,
then I'd just go ahead and kill it probably.
If it's a nice coin I'd immediately contact the devs
