Always need to diversify your portfolio
That's not true.
If a person (like OP) is ONLY investing $10 per month, then how would you recommend that person to diversify?
Some persons actually have a preconceived advice to give or what they may call standard advice, such that any case that arises will be greeted with the same advice. Some cases if not all should be treated cade by case. According to JayJuanGee, do you expect Op to divide $10 into 5 in order to diversify.

That's why many of us know that it could take years and years and years to build an investment portfolio, and a student might not have a lot of extra capital (or cashflow) but s/he can start to develop good habits by investing, and something like bitcoin allows a person to invest very small amounts.
I agree with you that $10 per month is NOT a lot, but a person should not be over-extending himself/herself, so they have to work with the budget that they have.. and
$10 per month for the last 9 years would have gotten you close to 1 whole bitcoin with a total investment amount of $1,080, and probably now days it would be better to invest $100 per week rather than $10 per month... and it is likely that someone who is a student will improve his/her income in the years after graduation.
Actually, a $10 per month is not totally poor for a student not from a buoyant background. But I feel if such person can devote time and learn trading, they can make $40 from the $10 within 3 months. Bitcoin might not give this in one year if bull run is not seen.
