Normally when new traders joins the trading filed they will track and trade the one market only. Firstly only BITCOIN , then they move to ETH, then XRP and after year or two they will notice that stocks exits as well, and grains too (yes you can trade this too, but not on Poloniex). As a trader I look for opportunities, and its important to search them between different assets.
As a trader you look at trade probabilities, searching for patterns and answers on "what is most likely to happen next", and sometimes you will not have an answer on one ugly price structure, simply no BIAS. That's the time when you have to move and open another instrument.
Why I am saying this? Because I get 5 request everyday for BTC .. there is not only BTC and there may not be easy HODL anymore. in 2017 investing was easy for crpytos, what could you missed, right?. but in 2018 things are getting a lot more interesting, complicated..
Back soon. GH
Let's see anyways,
