This is totally a misunderstanding.

Here's the explanation from BTER:
 
People were asking BTER urgently for withdrawals to participate the ICO before it's ending.
We tried all our best before the ICO to get the wallet synced but failed.
That's why I spent hours on the LISK chat room asking for someone who have a fresh blockchain urgently but unfortunately there's none.
In like 1 hour before the ICO end, the crypti wallet blockchain still stopped at ~90%, I knew there's no way to make it fully synced for the withdrawals.
I even asked Max if there's any way to process the withdrawals without the blockchain fully synced (like bitcoin), but he said no.
I also asked  if there's an online wallet so that we can process the withdrawals manually but none.
Right before the ICO ending, our users were requesting the withdrawals desperately. I figured out one way and I told people in the LISK chat room that I figured out one way.
I calculated the amount of XCR in the withdrawal requests and redeemed in one time in the LISK ICO and posted on BTT to let people contact us so that we could record their info for LISK redeem manually.
Until now our customers are happy with this solution.

Note1: I used the LISK ICO system for XCR redeeming. It's not from BTER's crypti wallet which was not synced at that time.
