Crypto 2.0 And Other Misconceptions

... Bitcoin was the first mover of proof-of-work-based blockchain cryptocurrencies. It is way out in front of its competition, and it will be a formidable challenge for any other currently-existing cryptocurrencies to overtake it, from the straight-clone Litecoins and theortically elegant Ethereums to the well-marketed but lacking in substance Paycoins and banal Dogecoins.

By design, Bitcoin can be adapted and improved without destroying the value of its tokens. If an undeniably superior method to operate a blockchain is discovered, it's far more likely that Bitcoin Core will implement it and its miners will deploy the patch than it is that they all sit back and watch Bitcoin die while another blockchain passes them.
