It shows how non-technical you are. People like you are using it as a gamble medium only but there are many who understands the core data structure on which these blockchains stand on and the problem that they resolve. Yes, these cannot be used as low latency data structures but that doesn't mean they are not efficient. They serve the whole big picture than that.
You need to be a computer science graduate with Finance background to understand what all problems it is resolving. So gamble and be happy but we are not buying your useless comments "People seem to forget...".

Educate yourself...
