The part the calculator does not show you
Held from the first day in this data to the last, TIA returned 0.153× — a loss of 84.7%. 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 TIA down 98.6%, from $20.15 on 8 February 2024 to $0.2853 on 2 April 2026 — 2 years and 2 months of falling. TIA has not been back to that peak since. Anyone who bought on 8 February 2024 is still waiting, 9 months later — which is the scenario a backtest showing a positive average return quietly averages away.
Note that TIA's best calendar year in this window is still a negative one (2024, -67%). There is no year in the data where holding it for the twelve months made money.
At 122.1% annualised volatility, TIA sits in the top band of anything on this site — the drawdown figures above, not the average, are the number to plan around. All TIA calculators →
Frequently asked questions
＋Would buying TIA on the first day of this data and holding have made money?
No. Held across the whole window the position ended at 0.153× — a loss of 84.7%. That is worth stating plainly because "hold long enough and it recovers" is the usual advice, and over the 2 years and 10 months we hold for TIA it did not happen.
＋What is the worst TIA has fallen?
98.6% in this data, from 8 February 2024 down to 2 April 2026 — 2 years and 2 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 TIA series starts in 2023; a deeper fall before that date would not appear here.
＋How much time does TIA spend below its previous high?
87.8% 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 TIA's best and worst years?
2024 was the best at -67%, and 2025 the worst at -90.6%. 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 2 years and 10 months of data enough to trust this backtest?
Partly. 2 years and 10 months covers real bull and bear conditions for TIA but not a full cycle end to end, so the extremes above are better guides than the average. Coins on this site with longer records give more meaningful answers.
What to keep in mind for TIA
TIA carried a very large unlock schedule after launch and has been sensitive to the modular-versus-monolithic debate swinging back and forth.
Posting data to Celestia is priced per byte and is dramatically cheaper than posting the same data to Ethereum — that gap is the whole commercial argument for the chain.
A backtest is one path that already happened. It shows what this plan produced through the exact sequence of prices TIA went through — not what a similar plan will produce through a sequence nobody has seen yet.
