Hello,
Could not find a clear guide on how to buy USDT in case of bear market. Example using Bitcoin.
Step 1
Go to the USDT tab in the main Poloniex Exchange Page.
Step 2
Here you will find a list of coins you can trade in for USDT, if the coin is not listed, sell your coin to get some BTC.
Select the coin you want to trade for USDT:
Current Coins: DASH, ETC, LTC, NXT, REP, STR, XMR, ZEC, BCH, BTC, ETH, XRP.
Step3
Sell your coin to receive USDT.
Hope it helps.
