If your capital is only $200 and you think that you have no other capital than this $200 that you will invest in Bitcoin, then you do not need to invest in Bitcoin.
I don't agree with you. If you have some money with you and $200 is the only capital you can afford to invest in Bitcoin, I don't see why you shouldn't invest in Bitcoin. If $200 is all the money you have and you can't afford to invest any amount of it in Bitcoin, then if you choose not to invest in Bitcoin, that's fine. And if $200 is all you have, you don't need to invest all of it in Bitcoin because that is not the right way to approach Bitcoin investment. The main way to invest in Bitcoin is to have a steady source of income, make a budget for your expenditures, and whatever is left, you can plan to invest what you can afford. Bitcoin investment is possible when there is a good understanding and good management of money.
I think @Bluedrem is sounding lost from his statements because if an investor has $200 to invest with, what does he need another capital for? Very confusing write up he made there. If an investor has $200 to invest with and he have plans of investing more, it's not bad if he has a source of income that he can take out a discretionary income to DCA weekly or monthly. Investing in bitcoin do not mean you must have a lot of money first, besides if an investor has $200 and feels that it will be problematic to invest all in bitcoin, the best will be to divide it into 2 (that is $100) and invest one part while he keeps the other part for emergency needs and possibly as reserved funds incase an opportunity comes for him to buy more bitcoin at cheaper price he can then buy the DIP with part of the money.
