The logo should have something to do with cryptocurrency and blockchain in it but it should not include actually cryptocurrency symbols.
The font of the logo should support cyryllic letters and say "Крипто Рай" (or КРИПТО РАЙ) if all caps.
The logo and business cards should look expensive but techy. We are selling to people with money, that's why i think purple could be cool, however I'm open to discussion. I love complex gradients and those can be used too, however logo should look good in black and white.
=== SOME IDEAS ===
Those are my thoughts on the logo:
a) Company makes money on cryptomining, so we could use some mountains, shovels, pickaxes, miners etc.
b) When you mine cryptocurrency, you normally use videocards to do that, so you may want to use some microscheme texture, or cooler propeller
c) When you are mining or investing in crypto you are monitoring stock charts that can be line charts or candle charts. Green candles mean stock goes up and red mean stock goes down. So only up arrows ;)
d) You could use anything related to heaven in the logo (Angels, wings, halos, harps, what else they do in heaven? :)
e) Blockchain is the distributed system of nodes, so multiple squares, cirles, heagacons randomly interconnected together, or connected one by one can be used.
!!! I’ve seen enough C and H combinations in different geometical shapes using negative space, so I think it would be really nice to come up with some image as a logo. You can play with “Crypto Heaven” text itself adding some wings, halos, harps, clouds etc !!!
