Another attempt:

On periodic table there is a continous route from potassium to silver:

K-Ca-Y-Hf-Ta-W(Y-2)-Re-Os-Ir-Pt-Au-Ag (au-ag is alpha squared)

We dont have a T in the image, so the answer is T.

Edit:

If s in Os does not count i can add scandium (Sc) in the route such as;

K-Ca-Sc-Y-....

Is the answer

M

?

or, , if the answer is easier, it is simply s, making the sentence grammatically correct and implying all cryptos by making that statement..

Currency spelling is read in the lined squares. For the other letters, i take english equivalents for greek letters, alpha squared taken as two a's, y-2 as w and altogether the image gives the following sentence:

"Chip work as a currency." This must be a credit card, shortened as cc, so my answer is

c squared

(implying cc just like alpha squared in the image)

I bought 300 LTC from Shdvb. Due to time zone difference the deal was closed next day, but at the end the transfer was successfully done. I hope to do business again with him..

Hi All,

I dealt with Shdvb on two different occasions today. At first transaction I bought 5 LTC. At 2nd transaction I bought 90 LTC. He is a fast and friendly guy. My experience of business was very good with him.

Regards.
