Today there are a lot of cryptocurrencies with high security level and Monero becomes less and less popular. Some time ago many people were talking about XMR like about very prospective token with bright future, but time passes and now I don`t think XMR price can reach all time high, only if there will be a huge hyip on the market like it was in the start of 2018
there is a lot of altcoins that are far away from their heights in January 2018, take for example ETH, but all others are in similar shape, XMR is on 20% of his heights, so that is not far from ETH, which is on 30%, and better than a lot of altcoins that are below 10% of their ATH - for example NEO, IOTA, XLM and between 10% and 20% like LTC and similar
so, it is in range with altcoin competition, maybe value at the end of 2017 was not reasonable in any way, and could be reached, but does not have to, even if BTC reach and overcome ATH, which seems reasonable at the moment
