Most people will advice you on what to do now that the coins are constantly losing value. But in the long run you will bear the outcome of your decision all alone so be. Careful on the kind of advices you take in as it will be only you getting affected in the long run. Selling now will only mean that you make losses on the coins as the market value is low, you are better off holding on to them till the market recovers
I agree with your statement. The decision to sell or buy tokens must be based on the inspection itself, because everyone certainly has different interests.
