I agree with you in terms of what certain altcoins have to prove themselves to definitely surpass Bitcoin, but at the moment the only reason Bitcoin has the leadership is because remains as the entry level to the crypto market, the one coin to get whatever other one. But as tech concerns BTC has been relegated because the infinite possibilities that turing complete languages and platforms can offer. Smart contracts and dapps are what is giving the value to crypto, not just the ability to become digital money, as what bitcoin value proposition currently is.

The Eth problem is big, but why you are not considering the power of EOS to shape the future of crypto development? I dont really know many of the coins you mentioned as the future top 10 and seems weird to me why not include EOS due to all the problems that might solve.
