"TOR" is not used as brand or marketing name here. "Torcoin" is. And "Torcoin" is not a registered trademark.
Perhaps it would be good to change the abbreviation to TRC or TCN something.. I don't see a clear benefit for using "TOR". Why keep it?
However, using that exact onion graphic by Tor Project is violating copyright law. In fact the onion should be removed from the branding alltogether. Again, where is the remarkable benefit from using the onion? It's just pissing off the Tor Project people. It's a really stupid move and for what? Nothing!
A good product needs a good brand. Cheap copycats are doomed to lose. TORCOIN should start deciding which party it belongs to.
Try to understand the logic mate, there are more than 100+ coins which have the abbreviation which comes down to a registered company or name, TorCoin is basically supporting tor browser and everything and there is nothing wrong in doing that.
There are more than 1 billion apps based on FB and not always you need to collaborate with companies to appreciate and build on that.
Using the onion again means that they are just appreciating the actual tor and there is nothing wrong.
Added to all these, as you ask benefits. TOR is a simple to remember name, and being tor already known to a lot of people it gives healthy pillars for the coin. Plus as you are talking about copycats, mate check the market volume for TOR and you will see the worth and respect.
Why are you actually against it ? can you elaborate ?
