Just sent you 100 STEM

In order to get 200 TMN (TranslateMe network tokens),
(For more info about it see the section called "Prizes/bonuses:" of my post)

you’ll need to have NEO-wallet and provide me your public NEO-address.
If you don’t have it yet, don’t worry, I published a post on how/where to get it (O3 wallet).

(O3 (Your gateway to the Smart Economy of NEO and Ontology). Introduction. Part 1. O3 wallet. A. Creating a new wallet)

or do your own research on the Web on how to get one.

Note that NEO-addresses provided by exchanges (like Binance...) will not work in this case (+ it's safer NOT to keep your funds on exchanges).
It's highly recommended to get O3 wallet.

just provide me your public NEO-address, and I'll transfer 200 TMN.

thanks for your interest/participation for/in the "Identify the molecule" league )
