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?
Well I'm depending on the situation of the market price whether I'll sell it 100% of it or 75%. If the prices are going alternatively up and down, then I'll sell 75% of it and keep the 25% like you're saying. But if it continuously rising up, I think it's better to sell it 100% for huge profits.
