If an investor is accumulating a total amount of $10 per week and the investor keeps to the plans of accumulating that amount, that is a good idea because $10 per month is about $40 and if the investor continues, six months' time, will be a total of $240.
You're right but is totally depends on what an investors earn on a monthly basis because if using that strategy there could be a possibility of getting yourself into trouble with the investment which can affect your capital at the long run, it doesn't matter how much funds you use for accumulation what should determine it is your monthly salary because there is no way you could advise someone that earns $100 on monthly basis to use $10 for investment on a weekly basis, because in no time he will ran out of funds and will be forced to sell of his investment so that's why every amount invested should be determined by your monthly salary which will allow you to be stable and confidence while accumulating Bitcoin
