If you are looking for other ways to make money from bitcoin asides from buying and holding then you can go into trading, although this is considered to be high risk in crypto but there's also a way to make profit from this if you start off with a small capital. Trading bitcoin can be very tricky especially for a beginner, you might end up incurring losses in the early phases but it's possible to get good results when you improve your trading skills.
Trading has put a lot of people into losses and it's not advisable for a brand new investor to start his bitcoin journey with trading because it's highly risky and not a good way to grow wealth for the future. Bitcoin is a long term investment and not a trading tools which is the main reason why anyone into bitcoin should be a long term investor in order to limit the risk associated with it in the long run.
It's easily said than done to make profit in trading and why will anyone go and start gambling with his money when he can just stay focus and use DCA to buy and build his bitcoin stash overtime. No matter how long it will take you to accumulate your bitcoin target, it's worth it because bitcoin is a store of value and a hedge against inflation. Whether, you start with small capital or not, you will end up in losses in the long run but bitcoin long term investment wouldn't put you in any losses, if you don't sell and use the right amount from your discretionary income to invest into bitcoin and build your emergency funds.
Traders end up with little or no bitcoin in the future and they will definitely, regret their actions but a long term bitcoin investor will have a significant size of bitcoin in the future.
Of course, a new investor should not trade for quick profits. But if we say that long-term investments will not lose money, we are starting him off with another kind of false expectation. DCA creates an average purchase price. But it does not create a rule that the value of his Bitcoin in the future will definitely be higher than the total cost. Similarly, an emergency fund can help avoid selling when necessary, but it does not change the outcome of the market. Remember that a person can either have the ability to hold for a few years and assume that his profit is guaranteed after those few years.
Many people may have a long-term mindset. But if he invests money that he may need in a few months, then despite his long-term mindset, he may be forced to sell when he needs it. This ruins his plan.
