The market is not what it used to be. I think people here are looking at it from a standpoint of a a year or two ago where just a few people traded crypto now all kinds of new money is going into crypto, wall street people, gold bugs, even girls I know who didn't or where interested in what a bitcoin was until recently.
Yes, the market has seen an immense grows but the entire volume is still tiny compared to the stock market, some companies are worth more than the entire crypto market. And the prices for bitcoin and altcoins do not represent their worth of today but are an investment into a future which might unfold.
And it looks like there won't be the ONE crypto in the future but many. Of course, a lot of them will go up but will also go down as fast.
