Everybody shows that he is Dimond hands, but scenario changes when you were forced to sell off your assets due to an emergency. People mostly sell their precious assets which they can sell quickly in this kind of situation. Unfortunately BTC is one of that assets that can be sold quickly at market price without any hassle. You just go to exchange and sell off to get cash for your emergency.
And it is because of this that people should not be investing money when they cannot afford to hold their coins in the case of an emergency, since there is no point in investing so much money in the markets if at the end you are going to be forced to sell your coins at the worst possible time in the market, now some may argue that it is impossible to know what it may happen in the future and no matter how cautious you are you could face several crisis at the same time which force you to sell your coins, and that is true, but most people cannot face a single one without having to sell their coins for a bad price, and this is a clear sign they have invested too much money in this market.
