Newbies or not, it is not advisable for any Investor to invest an amount that's going to trouble him or her into bitcoin. Bitcoin investment is best done with money you have budgeted ahead. One should plan his financial flow, and know which percentage that is to be invested in bitcoin and which should be used for other house hold needs. But as an investor, there are weeks or months where you have less expenditures in terms of family needs, when situation like this happens you can decide to be a bit aggressive in order to increase your bitcoin holding, buy increasing the percentage allocated in bitcoin investment for that week or month. This is a more sustainable way of being aggressive rather than using up money meant for other house hold needs in buying bitcoin.
It is good for anyone thinking about buying Bitcoin and he/she should be smart while doing it. We should never use money that we need for regular things like rent or food or bills. First we need to plan our money and decide how much we can afford.
Sometimes there may be weeks or months when we do not spend as much money on our household needs. When that happens it is good to put little extra money into Bitcoin. This is sensible way to buy more Bitcoin without risking our financial security. It is much better to do this than to use money that we need for our family. With this way of thinking about Bitcoin is good and focuses on building our investment slowly other than making quick decisions based on what everyone else is doing.
