I agree with Reatim, your vague advertisement is unlikely to attract anyone's attention. What exactly do you mean by "non-valid cryptocurrency"?
I am also confused with the meaning of "non-valid cryptocurrency" but maybe it is referring to DEAD coins and tokens which already have no value in the crypto marketplace. And if that is the case, isn't it dubious in the first place because why would anyone buy something that is already worthless when it would be so easy to mint a coin or to produce tokens these days. Anyway, I am just wondering on this offer so it would be good if OP will instead give us details here in the forum rather than in TG.
