If you don't need the money for another project or hobby or emergency my advice is keep it away in storage and when the card collecting bug hurt you again in 1 year or 5 years you will be a verry happy guy when you will open your storage box and see all these candy red cards
On my side i didn t buy cards since couple month.. my interrest is still present but i have a low interrest in it since couple time... i put it away in my safe until the bug hurt me again. I don't need money so i don't sell the cards.
