He needs to fall somewhat below 387 to match his lowest level last year because that was before he added paid YouTube supporters (or whatever you call them) that he claimed amounted to 100 at one point. If it’s down to around 50 by now, as they were new supporters who perhaps dropped off at a quicker rate, then he’d need to fall below around 840 to match his lowest level last year.
The level of support he’s got at the moment must create huge indecision for him. It’s a lot of free money to simply walk away from, at the same time it’s galling for him that he enjoyed support from 900 patrons barely two years ago, and now has to cut his cloth each month on a level half that, and declining. He’ll probably ride it all the way down to 100s doing as little as he can along the way, and mess around wondering what to do next. Maybe he’ll become a vocal proponent of universal basic income.
