Tom Lee, Chairman of BitMine, predicted at the Korea Blockchain Week summit that Bitcoin will reach $200,000 to $250,000 by the end of the year, with Ether targets at $10,000 to $12,000. He believes that Bitcoin will perform strongly in Q4, and the Fed's policy changes are favourable, expecting Ethereum to break its previous high, with the final price potentially in the range of $12,000 to $15,000.
