Its only a one-time work, after u done its process, u will benefit almost free-transaction for ur entire life on EOS network. If you want to make it easier, i suggest u to use Wombat on the Android, its allowed you to create wallet freely, u only need to pay (easier payment with Playstore option) when u want to copy the secret key and move to another wallet, wombat also provided u 10 times daily transaction.
Yeah, I thought that as well, but it is only an advertisement. At that time, I staked enough EOS to do many transactions per day and, in the end, I was forced to beg some CPU power on 3rd party services. And then
a few EOS forks appear and that's when I decided to move away from EOS. It's so unfortunate what happened to EOS since I enjoy EOS apps such as Newdex and EOS casinos.
