Hi there!
I am offering an upgrade of your Dropbox account from 2GB to 18GB using referrals.
All I need to perform an upgrade is your referral link. You can check yours here: https://www.dropbox.com/referrals
Upgrade will be finished within about 16-25 days.
Price is $20. I accept BTC, ETH, LTC, XRP and many more.
If you want to buy or ask a question, just PM me.
As I am a newbie here, first +2GB before payment.
