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 can understand this "idle" feeling. Having a couple of bitcoins is a good thing having more is the better, and it will not increase if sitting in a coldwallet . You might want to take a look at margin funding. Not a huge gain, but still some gains with relative low risk if you choose a bigger and better exchange.
