Once youve consolidated your portfolio into a good mix of different market cap coins and different blockchain sector coins, the next step is to maintain this variety with different coins. When researching coins, one of the first things to be looking at are the market cap and sector. If you can see that this coin has a good spot in your portfolio and you feel confident in its potential, try switching out some coins to modify what makes up your portfolio, as regularly adjusting your holdings will give you an advantage when trading.
