to be honest i dont really care if btc is the best, i know when btc price rises altcoin will follow it.
so do you think all coin except btc are not good? like ETH,NEO,XLM,XRP,NEM etc.
i know btc is the mother of all coin, because its the first, but we cant underestimate altcoin who come with great technology.
but for some shitcoin i agree with you, it can be test your lucky.
BTC is undoubtedly better, i.e. more sound, than all the coins you have named over here.
