I think you are giving much emphasis to the wrong aspect of unrealistic bitcoin speculations by non investors and traders. If you are Really referring to bitcoin investment, then you might be wrong about a person loosing all his funds. Bitcoin investment is a long term practice and records have not had such investors regret holding their funds.
You all got it wrong and tried to correct me, I appreciate it but I can not take your messages for my practice.
Investment in long term and holding for long term are very good but to do it well, you must have proper start that has many necessary conditions behind and if you lack them, you will very possibly get big troubles later. Then, even if you determinantly with your plan, want to invest and hold, you will simply not be able to do this. Oppositely and unfortunately, you might have to sell when you don't want to do that deeply in your mind, and do it for losses.
Another thing is storing your bitcoin safely for holding, and if you do it wrongly, your holding practice can turn to be a nightmare as well.
Your points are valid, long term investment requires proper planning and preparation, that is why we are ask to use our discretionary income , and make sure we have reserved funds also , so one need to understand the potential risk and strategies on how to minimize losses or negative impact, and one also need to ensure they have stable financial foundation to withstand market volatility , so that you won’t sell your bitcoin ,the whole essence is to buy and hold for longer period in other to have a substantial profit at the end of your investment.
