They'll all get attacked sooner or later. If they're going to fold up & die to some simple attack then it's better that it happens before anybody gets tricked into putting any money in. It's just testing their security. If they sink they're a witch, so it's fair, you see? You wouldn't want to put your money in a currency that's so vulnrable to attack that just a few people can take it down with little effort, would you?
If it's not a shitcoin, then it's just a little harmless stress testing on the network to allow the developers to see if their defences are adequate or if they could be improved.
Could I beg a favour of you? I'm not technical, so I'm not quite clear as to what's going on technically. It's the price I've paid for a peripatetic life: I read too much

Could you explain what the technical nuts-and-bolts are behind this "testing their security" as if I were a complete noob? Since this particular "harmless stress testing" is on its way to the implementation stage, I might as well scrounge for a lesson on how it's going to be implemented.
Thanks in advance.
