Having emergency funds is a good idea, but I don't think it's necessary to have it before investing. I think we can plan for that while investing. Having multiple sources of income is something I think is crucial for new investors because it will help them reach their financial goals and allow them to save for emergencies from their income.
In reality, through the journey of life, emergencies do not always happen to everyone so it doesn't have to be something that we have to worry about. Because besides being able to prepare when we have made investments with long-term goals through Bitcoin, emergency funds also don't have to be hoarded continuously because not everyone experiences emergencies every day. So just carry out the desire to invest in Bitcoin so that we don't feel regretful when we see the price of Bitcoin which has returned to making a new ATH ($111K+) this month by increasing sharply in a matter of days. And be sure that today there are some people who regret selling Bitcoin too quickly and also because they didn't want to buy Bitcoin when Bitcoin was still stagnant at $100K.
You are right, emergency doesn't happen or occur everyday but you should understand that emergency is not just a financial problem but rather emergency can be anything provided one is not expecting that particular situation at that moment. Moreover, emergency happens to everyone whether in Bitcoin investment or outside Bitcoin and it is very necessary to save up or prepare in case of any emergency so saying that emergency is not something we have to worry about, it is very wrong because emergency is something we should always keep in mind in whatever thing we are doing and it will also help one to be conscious.
