it all depends on the altcoin because every day there are altcoins that can reach 100% price increase in a day.
but keep in mind that this is only the hype made by the altcoin, and what I know is that there are no altcoins that are better than bitcoin.
I agree with you on that, it will be impossible for any altcoins technology to ever be able to stand with that of bitcoin, I believe that we all know Ethereum came as second to bitcoin, and when Ethereum came, they came as though they have a better solution more than bitcoin, but till date, no matter the market strategy being used by Ethereum, they have still not been able to reach bitcoin in everything.
Most of the altcoins we see reach 100 percent at one point is because they are still very low in value and they have low market cap, but in general, no altcoins has ever increase as much bitcoin has, even any one doubting is to even check CMC, they will see that bitcoin increase since it was created is quite higher than every other cons that may exist in the market.
