one character only can keep 30000 caps,you may need another characters or gifts.
I have such a gift course of 500 pieces of 30 thousand caps. If you do not agree with this course, do not ask for currency in gifts. (Usually, if you open gifts correctly, you get 30 thousand covers with 300 gifts, by offering this course I give you a bonus and save my and your time) Gifts you can store in a warehouse and receive covers when you need it. Each gift can contain ([25-1500 caps, various help drinks, food, stimpaks], trash for craft and very good recipes).
