Honestly, I think 99.99% of "cryptoinvestors" don't give a fuck about whether or not a coin is broken, because they are well aware that this is a game of pure speculation and greater fools. They would literally trade entries in a google spreadsheet, if there was a chance of it making them any money.

Before Verge switched to multialgo, the network was under attack, with a miner throwing huge amounts of hashpower on it, driving the difficulty up, then removing it, effectively stalling the blockchain for ages. This was the reason for the switch in the first place.

What happened was that exchanges stayed little sandboxes, because funds weren't moved in or out. This limited liquidity kept the price quite high, actually, especially for a coin which was under attack.
