Sry. My fault, I meant steem and steemit.

But I am also afraid that almost all cryptos will turn out to be big scams, or just turn out to be fails.

Not that I don't belive in blockchain tech. It will be used in logistics and in the future maybe as "money". I just don't see countries, banks or corporations that will invest in todays inflated currencies. They will make their own and start from scratch.
