I did a longish of jl777 holding's here:

Problem is he holds most the "assets" he "donated" to Supernet ICO are majority held by his own assets ie by proxy. And he has asked for 500 BTC for "2000 BTC worth" of his own assets.

If you are willing to pay so that one can get rich by:
a. buying a shit load of coins, pumping them and then dumping it on you
b. dumping an asset (or coin) held by someone

then yes you must buy the SuperNet ICO.
