I also have the same idea before but as time goes by investors are don't really want to spend their crypto for something they rather hold it than to use it.
So I think that only a small percent of investor or crypto holders are cashing out for the holiday season there might be another reason why the price is falling.
but for bitcoin to grow we must not totally hold as circulation is a must.and also the price today is bullying ,i hope this will continue for at least a week so we can have a good year end,but i dont consider now using crypto for buying gifts rather use Fiat this year like what i did in 2018.
