I would like to be able to turn auto renewal of Premium accounts off.
Some people might have spouses that are not tech savvy or do not know our password to the mail, so if something happens to us it would be better if people had to manually renew on a yearly basis, I think automatic is fine if you pay month by moth, but turning auto off would also be a great feature if you pay annually.
It could be as easy as making premium available without auto renewal on the page where you upgrade.

so far we were not able to accept cryptocurrencies, but we are working on this. I can promise you that we are not a scam company. :-))
I have a debit card so there is no way I'm giving them my info if you can't turn off auto payments. This and the fact that they no longer accept cryptos makes me see them as less legitimate and more like a scam company.
