Cryptocurrency is not time consuming, I don't really know why you said it's time consuming, you can be anywhere and you will still be trading, to buy a coin or to sell a coin those not really take any time, so I don't know why you think cryptocurrency is time consuming if you can explain.
How those cryptocurrency causes shock and death? When investing in Cryptocurrency, don't take loan to invest and also always invest any amount you can afford to lose, don't invest all your money, if you invest any amount that won't really affect you when you lose it, how is it going to cause shock and death?

I don't believe most of the disadvantages you mentioned above, most of then are not really valid, but I will be glad if you can explain more better.
