With the planning that you have done, of course we all want to encourage you with long-term investment planning, manage your cash flow as best as possible and don't be too emotional because your target is for long-term investment.
In addition, buy on the exchange and make a withdrawal when you reach $500 so that there is no waste of costs if you make a withdrawal every week. Hold and have the safest wallet, we will look at a bright future because BTC has a limited supply.
That's why we need to understand that investment must be done in a much more responsible way and there is no need to force it beyond our capabilities. When thinking emotionally and greedily in making a profit in bitcoin, someone will be trapped with unhealthy thinking skills and try to do something quickly to make a profit, but in the end we reach a stage of loss that was never imagined. In fact, when we use a long-term pattern, the investment method used should be much easier and we can slowly collect bitcoins.
Waste of costs is a problem for some people who may be involved in trading or investing, but the method you convey can be applied by those who buy bitcoin with a slightly smaller budget. Once $500 is accumulated, people can send bitcoins to a much more secure wallet, making the sending costs much more affordable for those on a smaller budget.
