but at $1, you're looking at $60+ million of fresh capital being injected
No.
Um, how so? How else is a coin suppose to make it to $75 million dollar market cap from $9.x when the majority of the coins are held by longs? That value increase has to come from new capital, obviously. Doesn't matter if it is from outside USD exchanged in or conversion of other alts, it's still new money to drive up the cost per coin.
With $60 million you could basically buy all the coins from every exchange many times over making the price go $500 a coin or something.
You have a very valid point in that it comes down to what existing "float" is traded from the outstanding coins, however, lets take it to an extreme. If all the existing holders of the coins wanted to sell at $1 (unrealistic I know), there would need to be $75 million in investment to absorb it. No one knows when and where people will take profits at, but I'd rather see a slow and gradual rise that allows weak sellers the chance to get out with profits and longs to pick up the available supply than a double after double with no support so when all the sellers want to rush to the exit, there is actually buyers waiting to absorb it all.
...and before anyone thinks of questioning my agenda here, I hold xxx,xxx number of coins.
