The part the calculator does not show you
Held from the first day in this data to the last, MNT returned 0.336× — a loss of 66.4%. Long holding periods are usually presented as the thing that rescues a volatile asset, and over this particular window for this particular coin, they did not. It is worth setting the calculator above to the full range and seeing that result written out before assuming time fixes an entry.
The deepest fall took MNT down 85.5%, from $2.7 on 9 October 2025 to $0.3922 on 1 August 2026 — 10 months of falling. MNT has not been back to that peak since. Anyone who bought on 9 October 2025 is still waiting, 2 months later — which is the scenario a backtest showing a positive average return quietly averages away.
One caveat specific to MNT: we only hold 12 months of daily closes for it, which is not enough to cover a full cycle. Any result the calculator gives you is a statement about one short stretch of an unusually eventful market, and the confidence you can place in it is correspondingly low. The coins on this site with six or more years of history give far more meaningful answers.
Note that MNT's best calendar year in this window is still a negative one (2025, -41.5%). There is no year in the data where holding it for the twelve months made money.
95.8% annualised volatility is ordinary for a major crypto asset and still several times a stock index. All MNT calculators →
Frequently asked questions
＋Would buying MNT on the first day of this data and holding have made money?
No. Held across the whole window the position ended at 0.336× — a loss of 66.4%. That is worth stating plainly because "hold long enough and it recovers" is the usual advice, and over the 12 months we hold for MNT it did not happen.
＋What is the worst MNT has fallen?
85.5% in this data, from 9 October 2025 down to 1 August 2026 — 10 months of falling. It has not returned to that peak since, so anyone who bought at the top is still waiting. Bear in mind our MNT series starts in 2025; a deeper fall before that date would not appear here.
＋How much time does MNT spend below its previous high?
92.3% of all days in this window sat more than 20% below a previous peak. Put another way, for most of the time you would have owned it, the screen showed a number lower than one you had already seen — which is the part of a backtest's headline return that the headline never conveys.
＋What were MNT's best and worst years?
2025 was the best at -41.5% (a partial year in our data), and 2026 the worst at -42.4% (also partial). The gap between those two is the reason a single average annual return is a poor description of this asset: almost nobody experiences the average, they experience one of the two extremes depending on when they bought.
＋Is 12 months of data enough to trust this backtest?
No, and that is the honest answer for MNT specifically. 12 months does not cover a full market cycle, so any result here describes one short stretch rather than a pattern. Treat it as a record of what happened, not as evidence about what tends to happen.
What to keep in mind for MNT
MNT trades partly on the size and composition of the treasury behind it, which makes it behave a little like a closed-end fund.
Mantle transactions are cheap because data goes to an external availability layer rather than to Ethereum directly — cheaper, with a correspondingly different set of assumptions.
A backtest is one path that already happened. It shows what this plan produced through the exact sequence of prices MNT went through — not what a similar plan will produce through a sequence nobody has seen yet.
