I think being aggressive is base on one choice though , even those that have gone far in their bitcoin accummulation and holding can also choose to be aggressive, is just most folks that haven't gotten to a good point in their accumulation and the once that are usually aggressive just to give their accumulation some boost . The reason why most people choose to be aggressive is because it will help time to fasting up things for them in their accumulation, but one thing is for sure don't over do it .
For instance a guy might earning $100 weekly, so he started his bitcoin accumulation with $25 weekly from his weekly earning which is around 25% . Then he decided that he want to fasten things up , so that he can increase the chances of getting himself some nice bitcoin stashes fast then he decided to use %50 percentage of his weekly earning instead, which is $50. At that moment that folks as become more aggressive in his bitcoin stashes than he used to .
Being aggressive should be based on the size of your discretionary income and the size of your emergency funds. Taking by your example if the person discretionary income out of $100 is $50 and he use the other $50 for his weekly needs, he can invest $25 easily without a problem but if you increase it 50% which is $50 because you want it invest aggressively, it might affect you somehow because you will be left without any funds after using the other $50 for your weekly needs. But if you use $45 to buy bitcoin, I think thia is a fair way of aggressiveness, because you still have extra $5 to spend on whatever you want.
However, maybe there are some folks that 50% of their income is their discretionary and they might be able to invest all of it into bitcoin due to their level of aggressiveness and it will not affect their bitcoin investment, but for me, it will be somehow like a burden. Someone with a large discretionary income can be more aggressive than someone with a small discretionary income. Imagine that another investor B collects $100 to like the investor above but his weekly expenses is $70, he can only invest $25 as being aggressive.
You are correct.
One of the reasons why some people dip hands into there Bitcoin even when they have not Accumulated enough or met there target of accumulation is because of being aggressive in there Bitcoin investment, some people become aggressive without having the necessary things needed which is good backup funds and a good source of income, I'm not saying one can't be aggressive in his or her Bitcoin investment but before you can become aggressive make sure you have a good source of income that will also reflect on your discretion income and a good backup funds now the reason for this so you won't get into a fuck you state where you will be lift with no option than to dip hands into your Bitcoin investment.
Every Bitcoin investor needs to have a backup funds because without it you may end up dipping hands into your Bitcoin investment one day.
Backup funds helps you when you hit a fuck you state, a state were you have no money with you anymore and you remember you have a backup funds you have been saving you just dip hands into it and keep accumulating your Bitcoin without interruption, one thing that draw some people backward in Bitcoin investment is interruption that leads to dip hands into there Bitcoin investment but backup funds helps to eliminate such things.
Being aggressive in your Bitcoin accumulation does not mean that one have ignored important ingredients like setting aside emergency funds and sometimes reserve funds. Being aggressive simply means how much of your capital you can ongoingly invest in Bitcoin after meeting your basic needs and other important requirements such as I have mentioned before. If you ignore the need to set aside emergency funds, then there is high chance of touching the investment and I would say this is the reason most people sell their Bitcoin to settle simple things that the emergency funds would have taken care of.
If I decide to invest 40% of my income into Bitcoin after I have set aside like 20% of my income as emergency funds, in a situation whereby the remainder can take care of my needs, I will be termed aggressive investor compared to someone who invest as low as 15% of his funds. This is what I see as being aggressive and it does not mean that someone who adopt this method will sell the Bitcoin unplanned because he has already take care of the situations that woud have made him to sell.
