Chopping off their heads does not work: cockroaches can live without one for as long as a week. Whacking them is no guarantee either: their flexible exoskeletons can bend to accommodate as much as 900 times their body weight. Nor is flushing them down the toilet a solution: some breeds can hold their breath for more than half an hour. To most, roaches are an unwelcome pest. Their presence is made all the worse because they are indestructible.An unwelcome pest is how many financiers and regulators would describe the crypto industry. Criminals use cryptocurrencies to launder money. Terrorists use them to make payments. Hackers demand ransoms in bitcoin. Many crypto coins are created simply so their makers can make off with the money.
