When bitcoin goes up normally a couple of other will move with it, a quick check daily to see more or less where you stand on the day - https://blockchain.info/

December 2017 was unusual with bankers, governments and everyone swarming onto Bitcoin. Media over-hyped the situation creating an illusion, sending people into frenzy buying (exactly the wrong time to buy). Safest is stay put learning, slowly growing in Superior Coin and Steem, when you feel ready, buy small amounts of BTC, ETH or similar and treat it like an investment asset.

If you have time/nerves to buy/sell in smaller crypto is always a good option to make a little extra @reonlouw
