Blackcoin multipool is the most evil idea.. you destroyed other coin and in the end karma will revenges you guys

There is nothing evil about evolution.
In fact to the contrary, the evolution of cryptocurrency is both desirable and necessary. It may displease some who bet big on the wrong coin, but that says nothing about what is good for the long-term viability and health of crypto. Eternalsoldier, I would suggest you are getting emotional in a misguided way, about the wrong thing. This cannot serve
your own survival very well as an investor in crypto. Consider that the anatomically modern human as we know him, of which you are presumably an example, i.e., 'cro-magnon man', at one time co-existed with the Neanderthal subspecies. The latter eventually disappeared, due to one or more of the following:
Competitive replacement due to anatomical differences (affecting running ability, hunting ability, etc.)
Rapid extinction by violence
Rapid extinction by parasites and pathogens.
Anyway, if you feel that crypto is or could become a good and useful thing - let nature take its course in gradually refining and improving the product.
