But the launch of the so-called meme-coin - a cryptocurrency with no utility other than for fun or speculation - has been widely criticised by industry insiders. "Trump's comments about not knowing much about the coin back up my opinion that he is making a mockery of the industry. It's a stunt," says Danny Scott, CEO of CoinCorner.

President Donald Trump promised crypto investors he’d usher in an era of legitimacy for an industry that’s long been relegated to the financial wilderness — dismissed by some mainstream investors as an highly speculative bet at best or an elaborate Ponzi scheme at worst.
