Yes, any user can assign the same currency multiple times for the Arbitrage AutoBots to trade with at the same time.

For instance, a user already has the Arbitrage AutoBots Subscription trading with a smaller amount of BTC for the full activation period of 15-60 days and wants to add on more BTC. The user first has to subscribe to another 15-60 days of Arbitrage AutoBots (as the initial subscription example above is locked in for the full subscription period) and then assign the additional BTC amount for the activation period to start the automatic trading.
