Tracking daily and even weekly fluctuations in the market is difficult, especially if you are new, so you will be more likely to buy coins and hold them for an average of one year, during this time you will understand how the whole market works and find a suitable trading strategy for yourself.
No, it is not difficult at all. It depends on the interest and goals of the individual. If he is willing to become rich in as short time as possible, he would do this much work with a smile on his face. Checking out the value of bitcoin or any altcoin twice or thrice a day does not take more than a minute. Indeed, it is not a lot of work. But as I have already said, it is entirely a choice of investor.
It may seem easy but it is not until you do it when you realize how difficult it really is, now you say that people will do that with a smile in their faces if that means that they'll become rich if they are able to become successful at trading but you will be surprised by the amount of people that are not willing to make any effort no matter the rewards, you just need to view the forum, people asking for coins that will grow many times over instead of looking for those coins themselves.
