earning $500 and investing just $30 a month shows that the investor is not intentional with his investment and i am saying this knowing fully well that some persons might still say that they are investing what they can afford to lose. everything that is worth doing is worth doing well and this includes how much we choose to allocate for our investment.
if you leave too much of your income as what you can spend, in the long run you might end up just eating from hand to mouth which means that you are just working to feed yourself with little left over for the future. by investing just $30 out of $500, you will have to do thus close to a year before you must have gathered your one month salary in bitcoin. that looks really poor to me. if i am earning $500 a month, i can boldly allocate nothing less than $150 for my monthly investment and in the long run work on increasing it. having a large chunk of bitcoin is the only way you can be certain of a good returns when you must have reached your investment goal and so there is no point investing so little when you already know about this.
redictable circumstances that can be analogized as emergency.
It is not about your income but your discretionary income because you are only to invest from your discretionary income. If someone earning $500, after taking out his monthly expenses and basic needs is left with an amount that is below $100 and above $50, I don't see anything bad if he invest with $30 weekly and use $20 to build his emergency funds.
Don't forget that we are not the same when it comes to responsibilities to take care of. This is why one need to invest based on his discretionary and the life circumstances playing around him at that moment. However, after he has built his emergency funds of at least three months of his income and reseve funds, he can channel that $20 into his weekly DCA so that he can increase his DCA amount. It's not by how much that you are putting into bitcoin that matters but it's for you to keep your bitcoin accumulation ongoing, consistently and persistently for 4-10 years and above.
Some new investors who don't have confidence in bitcoin can invest with little amount of money as low as $10, till he has built his confidence in bitcoin before he can increase his weekly DCA amount. It's better to accumulate in a whimpy way for a start, than investing with an amount of money that might not be your from discretionary income.
