I had long suspected it!
Often asked to provide audit results, but no answers came

Very sad.
Why you reviving a dead thread? look at the date of those posts.
Not sure what the OP did with his 2 BTC of Lisk on the ICO ...likely sold it
However, I got talked into 'reluctantly' getting 1 BTC worth of LISK on the ICO. BTC was exactly $475 USD
I think I figured. So that came out to 6,248.30 Lisk at the time. (currently staking lisk and gaining 40 Lisk a month,
maybe a bit less now...more or less, was 40 lisk a month, last I looked)
Thus with staking (came to that late), I'm at 6,331.35 lisk from that ICO of 1 BTC and staking....at current coin index chart price of $8.53 usd. (as of this moment)
do the math...best 1 BTC investment I ever did.....so if the OP kept his 2 BTC he doubled the above amount in profits.
Sometimes the blind squirrel finds the nut!
