Yes, when a trader trades with real money, he will know the nature of market conditions. A trader will know directly about the nature of prices and how the market works. When a trader makes real trades both fear and greed as well as having metal stress those play a special role for the trader to be efficient. A trader can be confident about what action to take in emotional areas.
If a trader is trading live then he will have to focus on getting to know the market which is not possible with a demo account. Moreover, a trader can gain proper knowledge about risk taking which is not possible to learn in demo trading as there is no fear of loss.
Although an investor collects bitcoins with a small amount of money and monitors it regularly, he can also learn about bitcoins in addition to real trading knowledge, which can further encourage him to buy bitcoins.
I feel that regardless of ones prio knowledge on trading before eventually deciding to go into full term Bitcoin investment, it's best one shouldn't mix up the two together as it has an high potential of draining down ones investment portfolio in the process. We all came from different background and our understanding on how to be better at our Bitcoin investments differs and somehow, if someone was once into trading, it's going to interfair in your plan to accumulate a certain amount of Bitcoin before a particular year or before Bitcoin gets to a particular amount amount if you're still trying to use part of your Bitcoin for trading purposes. It's not as though you might not be successful in some occasions but tampering with your investment goals based on an adventure that has a probability of yielding positive or negative returns doesn't look like a good bet with your investment.
The time and effort you would put into trying how to do a test run with a demo account and then going into doing trading could potentially be annersed in a more productive venture that will yield better profit which could be added to your investment portfolio and it goes on to increase it value. A proverd goes that
a bed at hand is far more better than thousands in the bush, Which directly means that an holding at hand is far more better than the probability that comes with trading part of your Bitcoin holding.
