I have some coins idling around in my wallet but I cannot bear to put it in hyip or risk it. But it is a waste to let it idle around. Yes. I have coins in some "lower risk" hyips to generate some interest which I'm prepared to write off. I also have some coins converted to hashing power in hashnest and BW.com but it has to be monitored else you will suffer a loss instead.

Unlike fiat currencies, I cannot park these coins into banks backed by governmental institutions. I put my fiat currencies in banks or blue chips but I cannot do it with cryptos.
So, what do you do with your idle coins? Let it sit around?
i just let them to stay in my wallet and wait for price rise, would be dumb to gamble( and probably lose them) them or so, i like to see more and more money in my wallet then price rises, so i won't change that and i will keep my idle bitcoins for longer, maybe i will keep them for some time and will sell them only if price will go to 1000$
