Hello @crypto.piotr It's a very great initiative a Great step taken by @project.hope

I did seen steemscan the day it was highlighted in the post from @steemitblog i visited it and as per my impression it looked very genuine website. A very simple user interface but amazing features inside means anyone can use it easily without any instructions.
And about the fixed fee it will not be great for normal users like me who withdraw a small amount of steem weekly or monthly because we will have to pay same amount of fee. Whales won't be affected as they are holding a large amount of assets they can convert a large amount of assets by paying certain amount of fee.
A my favourite advantages you don't need any KYC to use steemscan Just like on blocktrade used to be
So on overall basis it's great website less cons more of pros.
