Hello what you mean upcoming halving on the next 13days? Are you sure you are talking about bitcoin? It just finished last May and will take effect again every 4years.
It seem you are talking a different project.

All time high is always dependable. And the last price was 20k for some record on other exchanges. But the truth is, we are not so sure whether this surge is real and not manipulated. Going up or down, I think I will hold my bitcoin for a while. I really want a good valuation to it when I sold it. Of course aside from my trading funds.
