Yes no kyc means you can do 100 accounts and trade 100 dollars worth of coin 100 times. That would be 10000 dollars. That is a common money laundering number 10000 level.
Furthermore, there are scammers that open 100 accounts and trade among themselves and give each other good feedback. After 6 months, those accounts have good reputations and the scammer would burn them all with exit scams - usually buying BTC for PayPal and then doing charge backs claiming that the charges were not authorized.
This won't be possible if each account is tied to a unique person which is not possible without KYC.
For me KYC is protection, plain and simple. I don't know about the OP but I don't have any issues with regards to KYC. If you're a law abiding citizen and you deal with a company that requires KYC but at the same time is a respectable company that is approved by the government to do business with cryptocurrency, then I know my information will not be used for some scams. I think the purpose perhaps of this thread is maybe to put information to fragile minds the disadvantages of KYC. Well, 'sup to you to decide.
