I always tell myself not to use my Bitcoin from signature campaign. I received 0.2 BTC for July campaign. Left with 0.02 BTC in mid August. I receive another 0.2 BTC for August campaign. Used most of them last week. Left with 0.02 BTC again. :/. I mostly use them to buy cheap Amazon Giftcard, domains and monthly VPS hosting.
TLDR; I tell myself to wait for Bitcoin price to increase before I use them but I always end up using them. :/.
