When you send SBD or STEEM to @tipU with memo: invest it is treated by the service like a delegation. So for example, if you send 10 STEEM, it's like you delegated 10 STEEM POWER. The cool thing is that you can take back the investment (refund) any time you want. Now, this is something unusual because when you convert STEEM to STEEM POWER, you need to power down to receive your STEEM back - and this takes 3 months.
Now, the @tipU service allows to refund the investment without waiting because it's not using the invested STEEM (or SBD) to power up. Instead, the invested STEEM/SBD is sitting in @tipU balance and @tipU just "lends" it's own STEEM POWER to the user. The example below will make it clear:
And here's the problem @tipU is running out of juice :) the amount of invested STEEM / SBD is getting close to the amount of @tipU own STEEM POWER. It also doesn't help that @tipU powers down constantly to pay the curation rewards daily.
So we've got 2 options here:
or
I'm planning to implement the second option, because it will allow @tipU to grow and more users would be able use the service - both the vote buyers and investors, but let me know what do you guys think. If you're really against it, I won't force it :)
If you don't feel comfortable with the planned change, please feel free to refund your investment (send 0.001 SBD to @tipU with memo: refund) and, for example, power up and delegate STEEM POWER to @tipU. This way you have full control over your assets.
Looking forward to your opinion on this matter!
