I am always trading. Buy and hold is not my approach to investing. So would rather not move it in and out of a wallet each day I want to trade.
Once I hit a goal amount in the trading account for a coin then 50% of profits get moved to a wallet each day. This is then my holdings, but in crypto this hold could mean days, weeks, or longer...just never know. If I feel there is a really good opportunity in another coin.
