Should we buy the dip, hold on, or trade?

My own method is to divide the position into 3 parts:

1. Investment: can increase by more than 3-5 times in 3-5 years, but uncertain in 3-6 months

2. Speculation: can increase by 50% in 3-6 months, uncertain in the long term, sell to cash when reaching the target

3. Cash: including stablecoins, US Treasuries, NASDAQ, industry beta, can cash out at any time for living expenses

Every time I want to take action, I ask myself, which category does this action belong to?

Set the most suitable proportion for each part, for example, my BTC investment position has already reached its limit, so when I want to buy the dip I need to check if there is still room in the speculation position, if so, set a selling strategy while buying; if the speculation position is also full, it indicates that I should increase the cash proportion first.

Anything that doesn’t fit into the above 3 categories is being liquidated, and I won’t touch it again in the future; less is more.
