"Do you think bitcoin is the end game though? Or will some other better form of crypto take over?"

No, I don't think BTC will be the "endgame", although it could take its place as digital gold (see my article on BTC coexisting with BCH).

There are many cryptos both eager and able to take the crown from BTC (look at BCH, Monero) and Eth (EOS, LISK?)
