You cannot "destroy" crypto currencies. How do you destroy something that doesn't physically exist? However, if your goal is to reduce the use of cryptos then you might have some options: Probably the most effective approach would be to eliminate the incentive that lead to their use: The primary reason to use crypto currencies is to 'hedge' against violence. If a robber attacks me in the street and steals my wallet they will get the cash in it. But if my money is in crypto, even if they kill me, they will still end up empty handed! This reduces dramatically the RETURNS on being violent. So much so in fact, that Bitcoin alone rendered all weapons, knives, guns, ballistic missiles, etc. obsolete! That's why those who are attached nostalgically or financially to these antiquated systems are so much against cryptos. Bitcoin and crypto currencies provide an opportunity for peace and prosperity that we have probably never experienced in human history. So, to answer your question: In order to make cryptos "go away" you would have to find an alternative solution to make either violence, or violent, disgusting people disappear. And I haven't found any alternative solution yet. Do you know something?

As a sidenote: I find your use of 'we' and 'us' highly confusing. Who is 'we'?? And why did you not specify more precisely who you are talking about? Would love to see your reply! Greets :D
