Some wait for monthly power ups but it make no sense to me to lose a month of curation income. Also, a big bee doesn't do anything for me, doesn't mean anything.
It's personal choice though and if you'd like to wait then that's ok too, many do so. I'm on ahive daily so when I have funds I power up (my wallet shows that) and I earn more because of it.
At least you're powering up and not taking everything out like most.
