I am selling my H9 (maxed out standard version) and understand the de-register proecss and that the new owner will have an H9 max when he registers.
Yes, the new owner will have an H9 max when he registers.
What would like clarified is if I buy a new H9 (non max) will it effectively max out due to my previous algo purchases?
No, it will not max out due to your previous algo purchases, but you will have all of your previous algo purchases available.
Also, you will not be able to max out again. You can only max out once per user acccount.
