it hasn't been rising for a few days and that makes you worried, because you're missing out on all those litecoins and stuff? :D

I'm sitting on a completely not moving ZENCASH (well it's moving backwards).
And I'm thinking "Should I just sell?" and go chase other coin.....

What I've learnt from a short period of trading crypto - the coin that you are worried that is not rising - WILL start to rise almost instantly or IN 24hrs AFTER you've sold it.
Trading crypto - it's the best tragicomedy there is :D
