Waaay early on when cryptocurrencies were regarded as being possible alternative currencies it may have made sense, but now as they appear to have become more like extremely questionable investment products/securities, I’m left confused why anyone still has donation links for them alongside alternatives that provide, y’know, usable money (e.g. Ko-fi/Liberapay/etc.).

Are the donation links I’m seeing just a web artifact like the occasional Google+ share icon on some sites, or is there something more at play?
