I recovered


TXID


The amount is being sent to your Poloniex BTC wallet.

Please be very careful when sending cryptocurrencies, in most cases they will be lost permanently if sent to a address of a different coin. Please let me know should you have any further questions.

Poloniex does not not deal with fiat currencies (Money/ Cash/ USD/ EUR/ ect)

Tether (USDT) is a cryptocoin that is pegged to the US Dollar for more information you can go to : https://tether.to/

If you have USD (not the same as USDT) or any other type of fiat (Money) you would need to find a trusted exchange that deals with fiat currencies, exchange it into BTC (or another coin that is also on our exchange) then send the cryptocurrency to its corresponding wallet on our exchange.

If you have USDT (Not the same as USD) already then you simply send your USDT to your USDT deposit address.

Do not send USD to a USDT address, or USDT to a USD address.


Sincerely,
Poloniex Support Team
