1st and 55th are not compatible with , what we are looking into cryptocurrency here.
They are bought on 99design, made by people who don't know what is mining or crypto at all.

We need something recognisible.
At the end, this is coin right ?
Logic tells me that coins must looks like coins, they are not just a text with locker. We are not opening a Company here.
After all Name is CLOAK, and it is COIN so obviosly design must be COIN with association of cloak or COIN with Cloak Text.
28ties are closest to this design. maybe even better the latest that are submited

1 looks good.

2. Looks scary, like something out of Harry Potter.

I vote for 28.

Is that how I vote? Or do i need something else?
