I figured out myself there are 2 very important things to keep in mind when trading:
- Once you buy a (decent) coin never sell for less then you bought it
- Always keep Bitcoin price in mind and don't buy alts when bitcoin is going up or down fast. Bit the same what you're saying in this article.
Yeah, I'm learning to never bet against Bitcoin and always have a stash. I will add to it as I take profts from alts, but experience has taught me that Bitcoin can ruin 3 days worth of gains in a heartbeat.
