I mean I'm been holding my investment in Bitcoin and another cryptocurrency, it's really a good thing that I learned to have multiple incomes because now I don't really care what happens on the market since my goal is the bull run, I have no intentions to sell at this point since I don't really need the profit at this point, I just find out the trick since if you always in the market you're always gonna get tempted to sell your investment every time you see the market drop a huge percentage, also it is also a thing and wrong if your investment your only income to cryptocurrency because it is still a very risky investment in the end, it is surely going to temp you if you really are depending on your cryptocurrency profit. So make sure to make multiple sources of income or at least have savings before even starting to invest in cryptocurrency to avoid losing money.
Second - if you have an investment plan, then you should have a reserve budget instead of just investment assets. Moreover, it is not recommended to invest all your budget without having a reserve budget - it is intended to protect your long-term investment plans from some urgent matters. Financial planning is certainly recommended rather than just investing - but of course long-term investments will tend to be desirable if you are not really able to take advantage of the market in the short term.
