but if you clearly see on the transaction its 100% bitcoin address, sir o_e_l_e_o is correct, you might victim to a scammer scheme, I'm just thinking why would you do a large transaction to an unknown exchange, I'm sure its an exchange I hear of that before, why not choose well known, like Binance, or poloniex?
Next time, for the OP to transact with bitcoin. First, need to search trusted exchanges. Then, try with small amount first and see if it will go thru and he has the access of the funds. Don't go big at your first transaction to any exchange, even on top exchanges. I do that in every new exchange that I want to use with. You need to test with small value. Because at some point, you will make mistake, at least you only lost small amount.
This is very good advice
