I have been using poloniex and I don't have any complaints yet but I read that they are not giving back the stacks coins directly so how are they "distributing to their users"? What does it mean?
Poloniex doesn't stake the coins on deposit with them.
For example, I'm pretty sure
this is a Poloniex deposit address, and as you can see it has never staked a block despite having a huge balance for a reasonably long time.
However, Poloniex *did* hold BTC, LTC, and DOGE on the snapshot date, and so were able to 'dig' a fair few free CLAMs. It is those free CLAMs that Poloniex gave back to their users and that CLAM's OP is referring to.
That's a pretty cool thing, to give back. Do you happen to know HOW they were distributed, though?
