Besides bitcoin and monero, has the crypto and decentralized finance (DeFi) boom given rise to any sort of other illicit trade or past-time surrounding the thousands of altcoins in circulation on clearnet crypto exchanges, given that many of the new cryptocurrencies have new functionalities like smart contracts, staking, sharding (scaling), borrowing/lending, insurance, be-your-own-bank powers, etc?
Do any of the new coins and tokens present new avenues to proliferate illegality on the darknet that is wholly unique from simply barter transactions and payments as done with bitcoin and monero?
