Its mainly because people just "invent a coin" and then dump it in a topic onhere in the hopes they earn some money. Preparing? Having exchanges prepared? Mining pools prepared? Anything about how all this actually works? They know nothing about it.
Then either theyre lucky, nothing goes wrong, and the coin has a reasonable chance of a good life. Especially with a start like BWK had.

Or, like in this case, even though the initial launch was nice, something does go wrong and takes a lot of time cause the "devs" arent prepared, then cause "the exchanges" did "something wrong", the coin will most likely die after a few remaining cramps.

Bad news is easy to spread, bad things are easy to remember. In cryptoland, the miners encounter "a bad thing" and just move on to something else that gives them what they want, and so on and on.
Something bad happens, they cant get their profits out or their electricity bill out, especially if you're mining with say 50+ cards, and they wont touch the coin anymore. Bad experiences in cryptoland usually do not change back into good ones, as far as mining goes.

Preparing can only be done beforehand people, not afterward.
