Basically I don't mind someone's decision to diversify their assets instead of just bitcoin. Of course I don't want to elaborate on the potential benefits of diversifying them, but let's be honest that such an approach can never go completely wrong in your investment plan.
Diversifying one's investment is not even a bad idea when carrying out investment, but like on this thread, where we are only discussing bitcoin investment and how to manage one's investment very well, Investing in Bitcoin is by choice and not a forceful thing. Anyone who wants to diversify their investment can still do so, but only if they have a lot of money to do so. For instance, if someone receives up to $3k in a month, they can decide to invest $1k in Bitcoin every month while they invest another $1k in something of their interest and use the remaining $1k to pay bills. Well, the inflow of cash can still be low, but the person knows better how he or she can share the funds across any other investment they want to make.
