I know say many newbies like me are unaware of this and I hope this post enlighten you on this, so you don't repeat my mistake in future.
OP, some us has been a victim of this, personally I lost money because of this act, though I didn't know but it was out of my carelessness as we know every exchange has minimum deposit and it is written boldly where we copy wallet, although we don't really know why they choose it that way but then that should not be our major concern, at all time our utmost concern is first of all to check the minimum deposit of any exvhange wallet we decide to use so that we wont be victim of circumstances.
When I lost the funds I tried chatting the exchange customer care, they told me that they have checked and my intended deposit was below their minimum deposit and at such it can't be deposited in my btc wallet that they are sorry for my loss and all was history, though it was part of learning to me, is just that I learned in a hard way.
