I welcome every initiative like this, because I read so many times from users of this forum that crypto is not usable as a currency, because there is nowhere to spend it. The truth is a little different though, although these are mostly online stores scattered around the world, and buying some physical products has an additional cost because of the sometimes not so low cost of customs fees.
The page seems to be doing pretty well considering it has nice number of reviews for many listed sites, and that this is first time for me to hear about it. However, I must note that this is not currently the largest directory of sites (1036), because there are some who have more pages listed, but I believe it is only a matter of time before this data can change.
1. yes, at the moment mostly internet stores and services are listed on Cryptwerk.com
but i think it's a time question
2. We have more then 4000+ merchants of Cryptwerk. And our database is actual and clean!
we have a lot of fake registrations that we filter every day. if you compare us with Coinmap - it's full of scam and fake companies. Our data base is actual and fresh because of manual checking of each merchant!
