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?
For the shorter term trades I would usually do the 90 / 10 split. 90% sell 10% hold, but it really depends on the coin, this mainly applies to something I think will have long term prospects, rather than quick in and out.
