Why not do it this way ?
Since you trade mostly in altcoins, as soon as your make your profits, sell them to stable coins or fiats, close that trade chapter.
Coin stable / FIAT is not a good choice if you want to become a trader, because what will you get with a stable asset? better find the top 10 cryptos and invest there.
What do you think everyone ? is there a better pattern that can be practiced?
Patterns are always changing, there are no definite standards. You just need practice and practice to understand.
