No that quote means that you should keep an eye on you "enemy", that doesn't mean you should join them.
I keep a close eye on these ponzi schemes, because their collapse usually sends a shockwave across the entire crypto market and that means a very bearish market for a couple of weeks.
Indeed, you need to know what the landscape is even if it is a swamp infested viper pit. I couldn't agree more the shockwave and the bad press that these creeps give us causes nothing but trouble.....even for those who steer well clear. Cheers J
