Lets take the following example. You buy BTC at 6k and it goes up to 8K. Do you sell 100% of it or do you sell 75% and keep 25% in BTC.
What are your opinions / tactics?
In fact, my decisions may vary, depending on different circumstances. Including I take into account the prospects and potential of a particular coin, the situation on the market and my life circumstances, as far as I need money now. But usually I sell about 60% of coins, and 40% keep hold.
