Cryptocurrency growth in thousands of percent in just the last year???

Hi Steemians,

Just wanted to share this with everyone here. Just stumble upon this page and the numbers are astronomical. If I would have invested $1 in any one of these currencies a year ago, I would have thousands of dollars today!!! Why is this not popular yet???

Please tell me the numbers are real.
