certainly market doesn't move in one direction like wise bitcoin. Is possible that bitcoin may even take more time to make correction as an investor you don't need to panic, you just need to be patient. I will say is good to be flexible while waiting on what the market will do.I see nothing wrong if you decide to take some profit while waiting to buy the dip because the bitcoin market may make more dip for it to gather the momentum to continue to move in buy direction. Most importantly don't sell your investment because the correction will bring more opportunity and also remain while flexible waiting for the dip.
This your advice is very wrong because you are addressing different categories of individuals, there are people who are still in there early phase of bitcoin accumulation which there major focus should be on continous accumulations of bitcoin and to build up their portfolio. There are people who are into bitcoin for long term, which they have not accumulated the amount of bitcoin and there investment time have not been reach. Investors can only be thinking of taking profits out of their investments when they have a good amount of bitcoin in their portfolio and they have exceeded their investments timeline. Sometimes we should be careful how we throw some out some statements and also we should also know the kind of audience we are addressing to avoid saying the right thing at the wrong place.
