You can use "steem2wls" tool to crosspost.
Its your decision as to what to do but right now you can have much higher returns on whaleshares then Steem.
If i were you i would stick with whaleshares especially now that you get a lot of inflation. Inflation is going down fast and when it does you wont be able to earn nearly as much.
You can trade wls easily on rudex. Takes about 2 mins in total.
Thank you. I appreciate the comment. Seems like Crossposting is basically the only option I have, if I want to use both whaleshares and Steem. Might change my mind regarding crossposts, but right now, I don't feel really comfortable doing that.
