. You are welcome to improve it.
Now, if you decided to add an automatic coin control feature, then why not benefit the community wallet with it - set aside 1% of the S4C going towards the community wallet. If people aren't willing to optimise the results themselves, let them pay for it. 1% is nothing in the whole scale of things.
Honestly though, consider not adding automatic coin control - you'll take away what I see as a big part of HYP's addictiveness.
Fine-tuning your control by going manual, go in cruise control mode when you want it to; focusing on other things than stake control, widening the adoption.
There are reasons why there are cars with manual transmissions and car with automatic transmissions. There are even cars with "sport mode".
Autocoincontrol is not an either/or proposal.
The 1% mandatory S4C is a dangerous idea. Default 1% that you can deactive (whether you are in manual or auto mode) could be worth considering. But 1% mandatory if you don't want to go manual.. I wish you luck to convince me.
