I think it's up to you to decide, dig deeper into shiba and then decide, as @Tayeon said there's a lot of good things coming to shiba tokens.
In the event that you are already making a profit after holding for a period of time, it is not a bad idea to take partial profits. I also hold Shiba but it's my short term investment so when I hit the profit I set I will take profits, and maybe wait to buy back after it corrects. This is just my opinion.
