It's really close to ATH (in the USD terms). I don't know how much the existing ATH is, the first result in Google tells me it's $68,990.90 (per the Wall Street Journal), according to. coinmarketcap: USD $68,789.63. The highest price today was $67,791.37, i.e. only 1.5% short of the ATH.
I think it is very likely that we will break it quickly. This should result in a large increase in media coverage, which, in turn, may increase the interest of retail investors. But who knows, maybe it will be a sell signal for many people, but I doubt it.
