I honestly don't remember why I called them a probable scam. However, I never heard of this website and I can't find anything about them anywhere other than a few very suspicious random websites (some with fake reviews/comments[1]), so I wouldn't touch them with a ten foot pole considering that there are already many trusted mixers in the market and that they are no different than any other mixer and their fees are pretty bad.

https://faucethub.io/news/post/138Thanks for your thoughts, though what I have observed is, most of the reviews of this mixer I found in google are sponsored and paid obviously included the link above.
And some of the list reviews of this mixer in some site whenever there's blender.io, there's no bitblender.io which is unusual but it might be just coincidence? AFAIK bitblender is one of the oldest(if I'm not mistaken) and they are known for their reputation so there's no way bitblender will be excluded from any list of trusted mixers.
And also I can't find their ANN thread here that's why asked them first when they contacted me to have a mention of their service on my site. Anyway, I might be ignored them if they don't have ANN thread or so.
