No problem :) I've updated the @tipU a little so now you can:
- send / buy upvotes to others (or yourself)
- invest by delegating SP (100% paid to investors, no fees)
- send any amount of SBD/STEEM with memo: invest (works the same as delegating)
OK, enough of this ad - tomorrow I will make the #smartcash research, happy to mine it already :)
PS. Yeah, it was intentional ;)
