Boredom is a part of the challenge and how to get rid of it, it will be up to you. Some traders don't feel bored after all because they know where to get the excitement in the cryptocurrency trading. For long term investment, you can't avoid it because you need to wait more time for the price to climb up again and invthis case, patience is needed. We don't know what is in store for us this 2019 but there is always a hope for another bullish market.
Actually, it is a good time to reshuffle your portfolio
I understand why people feel bored, there is not much to do as no big price action has been seen for almost a week already (read, Bitcoin users are trading addicts). But there's at least two two reasons why you should not be bored at all. First, when the price stands still for some time (which is too long for the market), you can reliably expect the next movement to be huge as it happened in the past and is bound to happen in the future
Second, as I said, you can use these trading holidays to reshuffle your investment portfolio, i.e. sell coins that performed poorly during the crash and thus unlikely to show good performance on the rise, and buy coins which proved to be resilient to market hardships. And when you start doing that, expect the whole market start moving too. So you can, in a sense, lure market into action
