I totally agree to all you said here because you are right, depending on signature campaign only to build a huge stash of bitcoin is myopic because you are likely going to be out campaign at some point which might affect your bitcoin accumulation or might even put a halt to your Bitcoin accumulation journey, so buying and accumulating bitcoin through your discretionary income is more reliable because your faith is more likely to be in your hands than depending on signature campaign that can end at anytime.
The money from the signature campaign can be considered as an alternative source of income. I never consider the money from the signature campaign as prudent money and do not manage investments completely dependent on this money. Rather, it is an alternative source of income for investment and I consider these bitcoins as an alternative investment fund.
To achieve goals and be successful in long-term investment, you must have a prudent source of income and manage investments with that money. I even think that investment fund should be considered as your main investment fund. The bitcoins obtained from the signature campaign play an important role in achieving goals quickly in our investment journey and it is an alternative source of income, which is very effective in our investment journey.
