Actually, I don't know about these things. I came here to increase my knowledge and to learn about the topic.
But it seems that I should have some basic knowledge about ICO, STO etc.
Actually, I'm totally new to even cryptocurrency because it's ban in our country. But I bought some steems because of my friend. He told me it's just like online money that varies its value and if it'll go high then we can earn some profit.
I'm so sorry I couldn't give any review to the topic or couldn't add something valuable.
