I totally understand your concerns. Iota is acctually not made for investors it's made for machines and reality usecase in IoT. That's one reason (beside the tech) why that big companys are partnering with it. And Iota needs to create that for them ASAP, because they don't like to wait. That's why Iota is actually heading all their ressourcces to develop the protocol to make it production-ready.
But you should see it as an opportunity... invest while there's a bullshit wallet and laugh when that changes

And by the way... it can't be easily hacked. Yust if you use the same adress for sending, twice. But i (like every investor) agree it's actually not really good usable for humans.
