I agree, and that's why bitcoin will likely prevail and alts wont. They're just unnecessary.
Alts *are* bitcoin. You don't have open source software without forks. Altcoins are part of the ecosystem and without a doubt strengthen it. They prove that bitcoin is here to stay.
Mainnet BTC is absolutely the best store of value in all of bitcoin. There's a lot of shit bitcoins out there. Collect, play, learn, use.. with caution.
