Probably I am not the right person to suggest you, but how about enrolling in promising altcoin/token signature campaigns. Yes, it is very very difficult to find a good alt worth promoting, but I think if you get one, then the payouts are much better than Bitcoin sig. campaigns. In the past I have done Hashrush, Storm, Sapien and currently I am doing this Omnitude. And the total value of these tokens is much much higher than I would have got in a good Bitcoin signature campaign.
Between, your sig space deserves so much more than $100 per month. I know money is probably not your target, but any project partnering with you benefits a lot. If you want, I can contact some project devs about your signature space.
I don't really want to take the risk on tokens that could end up being worthless. I'm open to ICOs but most of them just seem like scams with only a pipe dream and some pretty pictures.
I would give you .110btc for the rest of the year. Current bitcoin value of 935$ 133$ a month is the breakdown. Let me know via pm if interested. This would be from June 1st to Dec 31st 2018.
We can work out any details in private but i'm ok with upfront payment of course.
I'll take the offer into consideration. Thanks.
