You’re right to some certain point, yeah if you go into investing in bitcoin with money you can’t stay without using for long you may end up regretting , in situation like this recent dip in market if you use such money like your house rent , school fee etc to invest the chances of you selling in loss is pretty high so avoid such .
When investing in bitcoin there are sometimes you need to be aggressive because if you continue to use only little percentage of your money , you will only slow things down like using $10 while you know you can increase it without it affecting you financially, like times like this with the market recent dips some folks tend to be more aggressive in their accumulation trying to make better use of any opportunity they got but without over doing it though which will speed up the pace and same time be in a safer side .
To build a good Bitcoin portfolio, in addition to buying regularly, it may be a good idea to buy a little more aggressively when the market is in dip. In this case, you should also have an idea of how much the investor's ability is. Even if there is an opportunity to buy at a low price, if the investor's financial situation is not stable, then it is definitely not logical to buy Bitcoin beyond his ability. If you have the ability, it is better to buy more, and if not, it is safer to buy within a certain amount. Those who are intelligent and prudent will definitely try to hold more by accepting the decline in the price of Bitcoin as an opportunity according to their ability. Those who can apply the strategies to hold Bitcoin correctly will be able to benefit more than others.
