Then from there I want to filter it by 1 step further by sorting by the lowest % from its All-Time-Low price.
With Coinmarketcap, click on Customize, you can choose From ATH, From ATL, %YTD.
That’s just about what you can get when it comes to customization on most of these exchanges, same goals with Coinmarket cap. It could as well narrow things down to the highs and low within a time frame but, wouldn’t filter according to dates.
Meanwhile, it’s easier to be old school and check out the coins within the top 300 as, the list is always largely published. Should you be looking out for some low market capitalization coin, you get to pick one and go old school on it, read about it, what network it’s built on, what protocol it operates, what’s it’s watchlist like, what’s the news on it and all that to get an idea that would prompt you to the next decider.
There's 10,000s low marketcap altcoins. To research on the top ranking ones ranked 100-300 one by one is lets say challenging. There's even old coins that haven't surpassed its 2017/18 all time highs bull market highs so these will be risky to hold. I am interested in new projects/trends that haven't experienced a bull market yet.
