Hey. hope's everything going well for you!

I have a small doubt, and it's that if I can use the same account (in my case, in Stake) to bet in more than 1 currency at the same time or if it will cause problems.

Thanks!

I will never recommend using the same account in multiple instances of the bot, even when betting in different currencies. Even for sites where the bets might not get confused, bet throttling/limits will probably cause errors.
