If it is difficult to speculate about BCX's motivations. It seems he is either bluffing to save his reputation, or perhaps he is attempting to instill some humility in the altcoin space. I dunno.
Humility, of which this superiority complex style trolling was done by trolls like Moneroman88? I'm confused as to what/why BCX is doing. Monero has been clearly and (maybe) unjustly trolled by some members on BTT(notably Moneroman88, Come-from-Above, and their clones), and as I think BCX knows that.....Then I for one don't understand the reasons for which he would do an attack against Monero. It seems like a waste of $ and a waste of time, with his going after a coin that has been obviously trolled against instead of the actual coins that are scams or the very least suspicious(That should be 90% of the ANN section)
