Some newbies don't like to listen to this kind advise not to sell in the low price especially when they need money, because they will think you are giving them wrong advise until they loss.
Why would anyone be selling there Bitcoin when the price is down what is now the relevance of investing when you want to sell like you said the best thing will just for you to hold, most times when you have other financial options then I don't think you should be worrying about what you are already holding, because nobody will advise for you to sell when the price is down because they know the value that comes when you are just patient and sell when the time is right because there is no way that the price will not come around.
If you know that when you sell it will bring you plenty profit you can go ahead to sell your BTC, because the reason why you are hodling it for long years is for you to make profit, but if you discover that it will not bring out profit to you , you can continue hodling to find solution to your financial issues, because you will surely going to make it when bull market occur.
And the profit is always the target and if not for the profit there is no use for you to make money and another reason like what is happening now about the market the market is down selling should not even be an option so have plan in case if things like this should happen then how do want to even compromise if you don't have any other thing to rely on it is very important for us to to have something to rely on for support when the price is down.
