And depend on the coins that has big market cap and that's already going to make you choose the best alt coins.
Because many did invested into for having potential and good road map.
actually coinmarketcap.com doesn't have any extra information other than what the exchange website you are using can offer you! and also their charts are pretty bad with terrible zoom and not so accurate data because of this zoom situation.
you are better of using the exchange charts instead.
and also the fact that coinmarketcap lists altcoins based on their market cap is a bad practice in my opinion.
Not to mention coinmarketcap should have ** ( significantly pre-mined) next to Ripple (100% premined) and Dash (massive pre/instamine). Also those scamcoins as well as others be shown in red. N00bs never even notice the asterisk anyway. It also doesn't mention coins that are centralized which n00bs don't even know why that matters. They leave out pertinent info and just add whether its mineable with an asterisk for noobs to get into mining. It's not for investment advice.
What honestly mean about asterisk i saw * right side in available supply in coinmarket cap what does it mea?
See, case in point. Do not use Coinmaretcap for Speculating it's really only goos for aggregate info if you already know what coins you are interested in. AFA what you should use well that answer is far too long for me to write out.
