When you started to provide the service, I used it, but not for long, everything was too imperfect. Yesterday I decided to return to you. Service has grown, got rid of childhood diseases. But it is desirable that you solve two more problems:
1 Currency of storage, now by default the funds are immediately transferred to US dollars. It is more convenient for me to store in LTC somebody in BTC.
2 Selection of the produced currency. There are times when during a few days, some currency becomes regularly profitable, I want the program to extract only it and exchange it when it's at the peak of the price. This would greatly increase the profit of extraction and would attract many miners to your service.
Thank you for your work I apologize if I ask too much.
Welcome back

and thanks for the important feedback.
We are working towards having a choice of base currency.
Re selling at "the peak of price" - we would love to know how you identify the moment of peak so we can think how to add this feature.
This is the usual behavior of any currency, on the growing or lateral movement, growth and then pullback.
Take for example Sumo.
On the first day when the pump occurred, I saw how all the farms switched to sumo extraction, then within 2 days as the price changed, they returned to it. You can even without turning to the charts of the stock exchange set up an algorithm in which: If the farms switch to some kind of currency after a while, then there is a chance that this action will be repeated and you can reduce the number of switching operations by extracting the currency whose growth we expect. For the peak of sales, consider the moment when it becomes profitable for extraction. In this method, there are both pluses and minuses, and therefore the user himself must decide whether he needs this lottery)
