You'd have to take into account the market in general. A better way of doing this would be:

"Did X rise more than bitcoin during that period of time?" and then try to find data from the last 5 years covering multiple ups and downs (very hard to do since ICO's are a rather new phenomenon).

You could take all coin launches with new innovation (speaking being that whether it was ICO or mined, people still had to invest through exchanges so it's not all that different) and see where they ended up for each year...

The reason why is, coins that came out in 2014-2015 barely did anything and I'm willing to bet the vast majority didn't really rise until late 2016 when ALL coins started rising.

As they say, a rising tide raises all ships. You need to take that into account, because the results will be vastly different depending on what the bitcoin market itself is doing. If all coins are rising, it's not hard to get on board with a new coin... if all coins are falling though, people won't be buying.

There's not enough data to make a true call on this sadly, but nice work man
