Have any of the investments made a return yet or have all profits been from trading alone?
The people that bought in at ICO paid $1 per TAAS and received two dividend payments which together are well over $0.60 per TAAS. All they need to do is sell to make huge profit, but why should they when they can make their investment back in less then a year, over and over and over, for doing ... well... absolutely nothing.
Theoratically, since part of the profit gets reinvested, dividend should grow larger since total investment grows as well, yet the amount of TAAS is fixed.
Two tactics you can follow: buy now at low price and sell just before dividend payout, or go long term and focus on dividend payouts and reinvest your payout by buying what traders dump.
The second is slow but fairly secure (as if anything crypto is ever secure...), the second may get you more profit faster but a growing number of traders aim to do exactly that, so competition will push margins down by a lot.
