That is misplacement and it is a very wrong thing to do whenever we are investing in Bitcoin in fact not only Bitcoin even some Investment outside Bitcoin, we should always do the right thing at the right time and we should always use what is required and what is needed and not the other way round and trying this, is a careless act and any investor that tries it will suffer darely because that is am improper thing to do as an Investor. Our discretionary should be kept available for accumulation and not our emergency funds because our emergency funds is categorically use and meant to solve emergency problem when they come up.
Anything that makes an investor invest in Bitcoin with his emergency funds, that's no longer investment because it has turned to gambling, because by that singular act of his, if any emergencies needs arises, his investment is doomed, so it's an act that should never be practiced or considered because no matter how enticing the buying opportunity is, a sane investor will never accumulate or buy Bitcoin with his emergency funds, because once the protection the emergency funds provide is removed, just know that it will only be a matter of when you are going to temper or sell it off when real life emergencies strike .
Most times some investors will say that let me just use it to buy now and I will replace it as soon as possible, but they don't know that they are gambling with their holdings with such a practice, which is a dumb way to go about your Bitcoin investment.
