If i bought using credit card, all my weekly dividen will be lock for 6 months, how about the reinvest 25%? Envion will automatic reinvest? We don't have to do it ourself right?
This is a very good question.
Technically your tokens are just blocked until Chargeback time of your payment provider is over (it is always good to get in touch with your provider and ask for chargeback time. Sometimes you can decrease it with further actions). During THIS time you receive divdends and reinvest will happen automatically, because 25% will be applied before paying dividends as far as I understood.
So the only thing you have to do is lay back and wait for unlock of your tokens.
Again: Maybe get in touch with your payment provider and ask for further assistance
