Please don't take this as a defence of what BTC-ARBS did, but...you shouldn't be risking money you can't afford to lose.  If you knew that you needed money to buy books, why risk it on some fly-by-night high-risk venture in the cryptocurrnecy world?

I've been burned a couple of times by various scammers (including BTC-ARBS)...each time I learn something new to protect myself.  I also NEVER put in more money than I can safely afford to lose and assume that I'm going to get scammed.  This is the Wild West of CryptoLand...you can't blame others if you get suckered into a scam.  BTC-ARBS was too good to be true...we all knew it at some point, yet like every miserable human, we fuckign got greedy and let that greed overcome common sense.

I'm sorry you lost money...but I don't have much sympathy for folks complaining they got scammed.
