I wouldn't say $2500 is easily attainable. That would raise the btc market cap from roughly $6 billion to roughly $30 billion.
If you think $24 billion is easy to come by, well then pm me, I have some bridges for sale.
Never said it was going to be easy, nor was it going to happen right away. Give it a few more years though, and it's definitely within the realm of reality.
$2500 isn't unrealistic, like some people who were preaching $1 million/BTC before. $2500 is actually attainable, and I can see that happening in the years ahead.
