reduce to 5 or maximum 8 coins. Tracking more than 5 markets at once will make for bad performance.
i track maybe 10, but there are always others that start going wild, i have a feeling im missing a profit by limiting only to few coins
You need to buy before they rise and maybe already have some sellorders set?
coinmarketcap.com is what everyone is using in case you didn't know but the site is lagging 10 minutes at least and some data is wrong; so it's not really reliable.
Generally you need to buy the coins before they start the steep rise.
Look for an accumulation phase. A slightly upward slope with medium volume is usually a good sign that it is gonna blow soon.
Although in the current market, it appears you can just buy any coins and sell it one day later for a big profit.
