Well to me I don't really see any thing wrong with that, starting with $10 if that amount is one's discretionary income since it is not advisable to invest money that will be needing for our daily expenses into bitcoin so instead of waiting for our discretionary income to increase while we are a no coiner or a low coiner starting with $10 discretionary income won't be a bad idea.one can be accumulating bitcoin with $10 and at the same time while working on increasing his discretionary income .
To me $10 is very small to be using in Bitcoin investment but it now depends on how an investor is using in accumulating Bitcoin, since $10 in very small to be used I think any investor who still wants to use it should be accumulating in every week at least to make the investment look serious because if an investor chooses to use $10 and he is accumulating monthly then his portfolio will be very poor and not encouraging, just imagine an investor having a total yearly accumulation of $120 is very poor.
The fact that an investor is doing DCA monthly with $10 does not mean the investor is restricted from employing other strategies whenever an extra cash arises so you shouldn't forget that an investor can only put his disscrettion into bitcoin. An investor can be doing his monthly DCA and still lump sum or even buy the dips and Moreover some new investors may decide to start accumulating with low amount and as times goes by increase the amount.I would not encourage any newbie to be waiting for there discretionary income to increase before they start accumulating bitcoin like the saying goes a journey of a thousands miles begins with a single step.so a no coiner should focus more on continuous accumulation of bitcoin using DCA strategy and can front load his investment whenever the discretion arises .
