You never lost with hold. Buy and forget your coin and don't track daily prices. If you track you can make panic and sell your coins.
I certainly not disagree with your opinion, to be fair I am almost only holding my coins but reading the news its the important thing to keep you informed what's happening on the market.
It would be much better if the investor will learn the art os staying calm under all sort of situations. If someone is just planning to hodl on for long then it is basically saving or inveting but not trading and he cannot earn as much profit out of hodling as from trading.
However, is a person does not wants to take risk then he must at least spend his money on bitcoin so that savings will do some good.
