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.
Everyone wants to build an investment portfolio where eighty to ninety percent of the portfolio will be Bitcoin and the remaining 10% will be other coins. My wish is that, although now my entire investment is in Bitcoin, I have not invested in any other coin so far. I have been trying to consistently invest in Bitcoin following the DCA method. Although it is not possible to invest the same amount of money at a certain time, still we try to continue this investment consistently by giving utmost importance to our investment. When an investor shares his success story it is really nice to hear that story and it motivates him to invest more. Mainly looking at investment related motivation I decided to invest continuously for long term and thinking of building a good investment portfolio in future.
