It&#x27;s a little more complicated than that. Assuming you are correct about the 6 Chinese miners controlling &gt; 50% of the hash power they could indeed collude and support a new block size.<p>When the first large block arrives the blockchain splits effectively creating a new currency. Old Bitcoin and New Bitcoin.<p>It&#x27;s the Bitcoin infrastructure in terms of exchanges and wallets that will decide which of these coins will be the winner.<p>Basically if you have 1 Bitcoin before, then after the split you will have 1 Bitcoin in each chain.<p>The market will decide which of these coins will hold value. It&#x27;s not the first time the blockchain has split.
