I think thats greed setting in
I believe this is the time to cash out if you are in profit already
How can you say it is time to cash out if you believe it is just greed setting in? No, we are not yet in the bull market stage but maybe we already are on the way there. Theres still a lot that can happen but good thing is we are already seeing upward movement in the market graphs.
If he bought his bitcoin at $3,000 - $4,000 price level. It is indeed a good time to cashout and sell. Profit are still profit, waiting for 20k USD once again is an optional thing since no one really know's if this incoming bull run will trigger another ATH surpassing the price of BTC in year Dec 2017 - Jan 2018.
Yes right, if you have that chance buying this assets when it went down to the bottom below $4k then you already have decent earnings, investors and traders have their own idealistic knowledge when to sell and when to hold, they have mindsets that will gives them the benefits of getting profits out
of this industry.
You have all the right to choose whatever pattern to follow while working for your benefits.
