On this moment my greatest fear are the exchanges. Every time again the BS comes from them. What I don't understand is why they can't or won't make their security up to the level where it should be.
There are so many exchanges for stocks, how come that they are secure and the crypto scene has all these problems? Are the exchanges scamming us? Are they really attacked by hackers? To be honest I don't believe that they are, it's an easy excuse and nobody really checks if they where really attacked.
Or am I not allowed to say this?

Because exchanges that trade in normal stock also have a potential for far more money, thus making them invest more. Also, there is a higher standard defined by law before you can open an exchange that deals with money and stocks, which there is not in the world of crypto.
And there is also the risk of not even getting any 'customers' after spending tens of thousands in security because crypto people follow the big mass like sheep and only go to the 'popular' exchanges. This is partly due to the number of sketchy small exchange and partly due to the fact this crypto world works based on mini-hypes.
On topic: what term are you thinking about going PoS? Will there be a lengthy development process to iron out some flaws in the PoS system and make the transition smooth, or will it be a quick copy&paste from other PoS coins to create a quick mini-hype (and pump)?
