can you tell what error?

Insufficiant vest.😯😯

Guess what, you don't have 750SP to delegate, the error is telling you that :)

but I have around 800 sp buddy.

try filling smaller requests, when steem is telling you you don't have enough, there is nothing we can do

🙁🙁

I see the problem, you are powering down, you can't delegate powered down SP

Oh! After removing power down Can I deligate?
