Can I run multiple bots to work on adjacent pairs?
Yes, if the option to sell the remaining coins (RC) is disabled, you can run an unlimited number of bots on the trading pair (on condition that the coins for all bots are available).
With the RC option enabled you cannot run bots to work on the same adjacent currencies. For example, there is a bot to work on the BTC/ZEC pair. You cannot create a new bot that will work on the usdt/ZEC pair, because there is an intersection on the ZEC cryptocurrency. However, you can create an unlimited number of bots that will not overlap, such as BTC/DASH, BTC/ZEC, BTC/NEO, BTC/BCH, BTC/BTG or USDT/XMR, USDT/LSK, etc.
