Once share for Bitcoin is finalised one has to cut his extra spending's if he want to regularly invest in Bitcoin. One can made cut on some dinners at restaurants or what ever he thinks is extra spending. If you never cut your spending's then you can't find cash for Bitcoin.
If you have been following up on this thread you would have known that some measures were discussed on that regards in other to keep our investment always running, so I don't think is nice telling or suggesting to an investor to cut down the rate at which they normally have there dinner, is a wrong approach, however instead of suggesting those ideas I think what you should really focus on is the best way to go about it rather than skipping dinners, however it has been advised for everybody who wants to emback on Bitcoin investment to always considered emergency funds and reserve funds very important because I'm certain that if someone has adopt those measures there is no way they would have been considering skipping some dinners in other to raise money and invest on Bitcoin.
The most important thing in investing is strategy and planning, how to make your investment long-term is completely based on this DCA strategy. Because here both old and new investors will benefit from using this DCA strategy to maintain their hold for a long time.
Strategy and planning is very paramount on Bitcoin investment because it educate you to understand some certain fact and also the importance to have a timetable and the needs to abide by it, having said all this things I think I would strongly disagree with you concerning your understanding about DCA strategy, actually DCA strategy does not force you to hold your investment but on the contrary your determination, desire, planning and passion is what makes you to hold your investment, so DCA work is just to help and make your investment smoothly and reaching to your desire points.
