If you have been hodling around the 10k price point, I think that it is best that you harvest the bounty that you deserve for your patience. Constant hodling wouldn't get you nowhere but FOMO, remember that prices could go down and this is your chance to get a more than decent profit from your bitcoin. Buying at this moment with the current prices for long term is a good thing but remember to take out the other bitcoin that have been sitting there before buying a new one.
I agree, though the price could go up more but the best way for you to have some profit if you think that bitcoin price will go down is to sell some btc in your portfolio. In this kind of way, you will avoid having regrets if the goes down and also if the value goes up because you already have profit and then you also have some more in your portfolio right?
And for me before buying bitcoin at this moment is really good because the chances of it getting a pump are high because of this year's hype.
