Well im putting down 65000$ so kinda worried 
That is a lot of money so I understand why you are really cautious over the sale. What I know is that just one confirmation is enough for the transaction to be completed but exchanges usually wait for more before you can do something with your bitcoin. Just like what others are saying here, transacting with that big amount of money can be so risky but then if it went through then it is okay.
I do exchange when it has huge of assurances in return, because exchanging is too risky and have to be aware the consequence in order to evade from loses. It usually used by many who has lack of fund in btc , so I think exchange is liable way to abrupt btc appropriably.
