Something similar happened to me, with the Wirex (card) token, WXT... I didn't buy them, but I was "earning" them on their platform and it grew to a nice amount... After that, they limited withdrawals (or exchanges to other tokens) from X amount of WXT... And guess what, they were moving that min. limit every week more and I never reached the amount for exchange... So, I just left it to die...
Dirty games from centralized exchanges... Watch out... ;)
I have picked this post on behalf of the @OurPick project which will be highlighted in the next post!
Yes, it is a lesson learned! Those centralised exchanges are very sneaky!!
