Some important notes about analysis
1. Analysis was done from 1st of January of each corresponding year till 31st of December of the same year

1. KSM, AMP, SHIBA ICO price was not found, therefore the ICO price was used from the earliest historical data from CoinMarketCap/CoinGecko

2. n/a means that a coin was not released that year

3. If a coin was released, for example, in July 1st 2018, then the analysis of that year was done from the date of ICO till 31st of December of the same year

4. Coins were sorted from the most ROI from the ICO date till 30th of October 2021

5. Bitcoin didn't have ICO, ICO in the table for BTC means the first day you could have bought it, which was $1 for 1309 BTC, same with XRP, Uniswap, Monero, they had no ICO

Key takeaways

1. Bitcoin has the most ROI from ICO date, but compared to other coins, gives less ROI each year, still a solid investment
2. Ethereum gives better returns than Bitcoin, but is worse in Bear Market
3. Shiba Inu has pumped only this year. In 2020 it lost value significantly, which means maybe after this bull run, it won't give any ROI anymore. Still hard to analyze with only 1 year of history
4. Axie Infinity, Solana, Kusama, Polkadot, Helium, Aave, Avalanche, Pancakeswap, Uniswap, Sushiswap, Injective Protocol, Arweave all were ICOed in 2020, and in a span of 1,5 years they gave insane returns, if they continue with the same pace, you can 10x your money in the future
5. AMP ICOed in 2020 and is the only coin in this table that gave consistent negative returns
6. Our beloved Algorand have a negative ROI from the ICO, but if you were buying the dip, you should be good
7. Litecoin is like a little brother of Bitcoin that doesn't get any toys. It gives consistent positive ROI but compared to others, it is really little return
8. Technically almost every coin has pumped at least 500% this year

EDIT1: NANO price was 0 at ICO in 2015, this means the return is infinite. But there was a cap for how much you could have gotten, in the evening I’ll fix it, we would count it as it was ICOED at 0.001

EDIT2: Nano ROI was fixed

EDIT3: AMP ROI was fixed

EDIT4: Looks like i got into news, lol
