I completely agree with you on this just as they say where our treasure is that is where our hearts will be, many usually say that we should buy and forget about it and it is not as easy said than done, perhaps there is nothing wrong getting updates of the price of Bitcoin and that doesn't make you less than an investor provided that the investment plan is for long term and they didn't buy with the money they are supposed to use in sorting out their important living expenses for quick profit maximization, but a part of their discretionary income they are willing to invest over the long term.
Most of the time, we lose our assets either to hacker, scammers or simply losing excess to our private storage, this outcome can be traced to lack of follow up with the market and a reflection of the level of disconnection between the investor who just follow the trend of buying Bitcoin and forgetting about it as you stated.
For ultimate goal one need to be actively involved with the market, to know what exactly is happening with the esset market and being able to make decisions that can help safe some situation at times, most especially when one is holding high volitile cryptocurrency assets.
