So we draw conclusions:
1. The exchange YOBIT does not accept coins.

2. The explorer does not work.

3. The site has already been sold.

4. The result: it is a great pity that we were deceived

5. Developer welcome to hell.

Yobit chose not to add it, as is increasingly common nowadays, regardless of whether the fee is paid.
So perhaps attempting to extort money by PM from an innocent person representing an ICO shows that
you are more than welcome to Hell.
Appeared finally! How good that you have a conscience. Where were you before? You are waiting here. How are you going to solve the problem of offended minners and investors?
