If states truly would want to get rid of cryptocurrencies

If countries really want to remove electronic money, it will have a major impact on the world economy. Corporations, companies that invest in electronic money will go bankrupt. Many will be unemployed and the world currency system will be overturned.

however the developed countries promote and support cryptocurrency as cryptocurrencies are benefiting them more than the developing countries, so there is a division in the united nations consil, which prevents state sponsored 51% attacking as being legal.

Why would they "destroy" cryptocurrency? Countries would be burning their resource for nothing that way. Besides, there an easier way to destroy it. Simply ban any activities related to cryptocurrency. I'm sure the number of users, hashrate, and price would drop drastically.

and what makes it worse this cyber weapon would then be able to eat more and more as each destroyed cryptocurrency would make the attacker even richer, which he can invest to have even more hashpower

What??? How does each destroyed crypto make them richer? You're being absolutely nonsense here.

they would easily be able to do that,
it costs just 6 billion to destroy bitcoin with a 51% attack

again going back to the basics of bitcoin and blockchain technology and one of it is that bitcoin cannot be destroyed it is distributed, so no matter how much money you use or how powerful you are you just cant destroy it!
