I don't think that any altcoin can beat bitcoin. Bitcoin is the father of all cryptocurrencies, they might increase in value but it will always be below the value of bitcoin, that's just only based on my opinion.
I agree with this but I also wish the market wasn't so dependent on the success of bitcoin. The recent downtrend has destroyed a lot of decent altcoin projects. Bitcoin will always be king but whew, I wish alts could have some independence.
