Logan Paul has been acting a little oddly lately (well... obviously, but not in the usual way) and I reckon he's headed for a fairly epic breakdown. Both of them should take their money, invest it sensibly, and run... before their popularity comes crashing down even with their core fans.

Basically, at some point their core fans are going to grow up - they don't have the chops to adjust to an older audience - and they'll be too old themselves to attract new youngsters forever.
