I hope I will still be able to type, when I'm 90 - but I think, there will be new solutions developed by then ;)
Well, if I didn't pay for my votes... I have bought some Steem over the past few months, and I am buying votes at Smartsteem.com, because that way I get more for the Steem, than if I would convert it all directly to Steempower ;)
I don't know, how this will work from now on, but if the revenue is too less, I will convert it all to SP and my earnings will get back down to "normal" :)
