When it comes to bitcoin investment, we should not invest all of our money in it so that we will always be able to solve our financial needs when they arise.
This discussion has been treated more than ones here, so I believe every investors or a beginner should be able to understand the concept that keeps their investment healthy and running however I believe this is one of the reasons why at @JayJuanGee introduce the method and the reason why an investor should have an emergency funds and also a reserve funds was actually because of a situation like this so that with a proper utilization of it an investors could hardly run into a problem no matter how it may be, however just like you said is not an investment wise to put in everything you have on investment because with the lack emergency funds or reserve funds their is a big chance of getting into trouble on the process.
For me I don't see any difference between what you are saying g and what mayor of ogba is saying. You both are saying thesame thing, if you read down to the end of his comment you will realise that he said about emergency fund and accumulate strategy which he mentioned also DCA to be presise. So both of you are saying thesame thing.
Everyone who has been in this thread for so long should have known more about emergency fund and it's important so needless of well knowledgeable member to ague about it, rather you should be in good position to educate more newbies about it. Emergency and reserved fund is ideal for any Bitcoin investor to succeed in his accumulating process, but not advisable to over due it in a manner that wit will affect us.
