Risk is part of life and that is true for investing too. It is smart to know that Bitcoin like any investment has its dangers. Idea of holding Bitcoin for long time if we truly believe in it is good plan. This helps us to deal with short term ups and downs by focusing on Bitcoin's future growth. You are right that even if it seems expensive now millions of people still see its value. Believing in ourself when we invest is very important in markets that change a lot. Like you I have also said that many time only invest money we can afford to lose. This is key for managing risk especially in crypto world. Sticking to planned approach can really help our investment succeed and last over time.
In any investment there must be risk involved, it can be high or low risks and every investors should identify where the risks lies in the investment that they choose. Specifically Bitcoin investment has very low risks and the risks has nothing to do with Bitcoin itself because it has proven to be a reputable asset, a store of value that can be trusted to give profit returns on the long term. Bitcoin investment risks are external, like protecting your wallet against hacks, scams, securing your seed phrase from theft and misplacement. Where you can face risks in Bitcoin investment is if you plan to sell on the short term, Bitcoin is volatile and you might sell at a loss if it dip when you want to sell off or to take profit. I don't see any risks involved in Bitcoin investment if you are on DCA method of accumulating, except you don't make provision for your basic expenses and emergency funds.
Risk is there and we can't play fool around when it comes dealing with our investment since any wrong movement might cost us lots of money and for sure that its hard for it to recover it in short period of time especially that we lose a lot from bad choices we made.
But if they deal with to HODL Bitcoin I guess the risk is less and we don't actually need to do anything especial actions since what only thing needed to do here is to buy Bitcoin then hide it for money years. What we are going to pay attention after that is to protect our wallet from any possible hacking and other exploits. I don't recommend to sell short because there's really nothing to get from their in in long run and for sure that they would miss lots of opportunity and they might regret their decision for not buying then HODL Bitcoin especially if Bitcoin reached for another huge ATH.
