For a few days, the option to donate with paypal is no longer available, the only available method being bitcoin. Paypal was available as long as it did not require identity confirmation, but given the blockages that appeared on the last accounts used, we are forced to stay exclusively with bitcoin. We are aware that bitcoin also comes with higher commissions, so the advice for those who want to donate is to do it less often and in large volume, so as not to lose much in commissions. There are tutorials in the wiki area for bitcoin donations, if you think you can help with a new method or updates on current methods, you can open a ticket.
