Yes, I personally want that some regulations should be there in Crypto market. This will help in building trust for Crypto market.
I also have nothing against minor regulations that help keep out scammers. The essence of the blockchains should not be attacked.
There may be some standards in the medical field like this, but I think they are created by the medical blockchain companies themselves. Aimedis seems to be playing a pioneering role here
Apart from regulations, some security issues also there, l know blockchain is secure, but I am taking about exchanges. There were some attacks on even top exchanges.
