Actually I don't see any problem for doing it especially if you are on need of immediate funds. I understand that we need to have build a emergency funds so that we can cover those emergency situation that we might encounter in future. But not everyone could set this up as fast as we think since there are people starting their journey pay attention first their Bitcoin accumulation and later on their emergency funds set up will come late.
Let me explain this for you in a more life applicable example,
let's say a person is travelling with a speed boat to a very far distance and is stressing the fact that he/she needs to pay attention to securing a ticket for the ride and neglect demanding and taking along a life jacket for the journey with the mindset that he would ask the captain later on course of the journey to provide a life jacket for him, something he was supposed to wear from the onset of the journey. Now what if the captain doesn't have any excesses on the boat and the boat capsizes before they arrive? you see the person just killed himself because of neglecting a very important factor of his safety on the trip?
This is applicable when we start off our accumulation journey for a long-term without the plans to grow our emergency funds alongside our ongoing accumulation journey and leave it for a later time, the risk of real emergencies chocking us increases and without the backing of emergency funds, our investment is vulnerable, and we may run out of options and turn to devour our investments for survival, which is a very bad practice.
What's important is the lesson they learn that emergency funds is really important on their journey, so that next time they would never heavily got affected if there's worse situation happened since they are more prepared for second time around.
People could start over again and they should do better decision next time to succeed and make sure that there's no other things would bother on their next accumulation phase.
Starting all over again doesn't guarantee that they would do the right thing and there is no thing as probation in your accumulation journey where you just go to test the waters, then crash and get more prepared to engage again with more caution, although some people might tend to learn from their mistakes and get better in their accumulation journey, but there are mistakes that could just be avoided by doing the right thing early enough, so we do not necessarily set traps for ourselves by our negligence, hoping to recover and try again when we could be progressing more on our accumulation journey if we had been more precise with our patterns of engagement.
