I just did a quick sweep to see how much coin I'm hodling at the moment. OK, so it wasn't so quick, because I kept remembering other places I'd left some dust. I also had to look up what the OMG airdrop was a couple of weeks ago, I didn't hear anything at the time, but when I looked at my ether wallet, I found a small amount had been added, which is nice.
Steem - 1974.914 SP and 15.761 SBD (total 0.46167267 BTC)
Bittrex - 0.00267093 BTC
ether - 0.0483 ETH and 100 PLR and 0.00836 OMG (total 0.00446351 BTC)
Various BTC dust - 0.001218 BTC
Various LTC dust - 0.00563 LTC (0.00005929 BTC)
Bitconnect $120 dollar loan outstanding and $3.97 and 0.01354774 BCC (total 0.02624045 BTC)
Which all comes together to be worth just under half a bitcoin. The largest part of it is not liquid, though - the Steem power would take 13 weeks to cash in and the Bitconnect loan won't be repaid for another 9 months, but still, it's good to know what it's all worth.
For people reading in the far future, this was on a day when BTC was trading just under $4800.
