Always hodl the media tells us, never let go. And yes... there are some of us that have taken this message to heart, including me. However... there comes a time when you need to consider taking profits, after all you don't have the purchasing power until you actually liquidate your holdings. I'm not saying you should cash out of bitcoin before it goes to zero, and I'm not saying bitcoin will go to zero. However there's a lot of speculative crap coins out there that won't be around for much longer. So knowing that, you can make good money SHORT TERM trading crap coins and use the profits to buy good coins like bitcoin, eth, litecoin, ect, and long term hodl those. Yes, there's a chance your little obscure coin goes to the moon, but most likely not. Overall it's okay to keep your funds in a store of value, but not a crap coin.
