Investing a decent amount is also another way to say invest with an amount you can afford to lose. Even if one is responsible or irresponsible, he/she should know that it's very important to invest with an amount that they can always afford to risk. Everyone has an amount that they can afford to lose, but most people don't know.
I don't know if I'm getting you right but why do i feel that your perception on Bitcoin investment is for trading because when you advised him to use the only money he can afford to lose, perhaps indirectly you are saying that there is a higher chance for him to lose his money Bitcoin or in other words referring to gambling investment, however in as much as nothing is guaranteed when it comes to investment but with Bitcoin success is certain if you are ready to hold, so actually the risk you are talking about should be actually dependent on the kind of investment you are talking about because if your pattern is for a long term holding I wouldn't use the word risk because it seems that you don't really understand or know the potential of Bitcoin you are investing on.
Any money you invest into bitcoin should come from disposable income.. so by definition it is extra money and/or money that you can afford to lose.
Your bitcoin investment could go to zero, so any money you invest could be lost 100%, and you should be prepared for that possibility with any money you invest into bitcoin.
Of course, every investor should make a decision to invest in Bitcoin based on holistic considerations. Overall consideration here is the possibility of high profit or investment loss. Consideration of disposable income as capital and the expectation of potential profit associated with it certainly helps to consolidate the consistency of each buying. Future determination of hard-earned income and the decision to hoard Bitcoin is definitely going to be positive as the system has often cheated one following the historical footsteps of the local currency investment journey.
An investment decision with potential returns like Bitcoin and its past price history is certainly a beacon of hope for small investors like us. Although you always say it can be high and it can also go to zero. Your whereabouts must be reasonable because none of us are sure where its value will go. But I think behind the negative attitude we must keep the positive influence which can encourage us to accumulate more Bitcoins. Long-term trends in holding and holding during bullish and overbought each dips.
Your whole post is a bit weird and unclear laijsica, yet it may be worth clarifying that one of the reasons that any of us might consider the possibility that bitcoin could go to zero or to have some kind of a negative rather than a positive performance outcome is so that we temper our investment amount in order to account for those kinds of considerations.
Sure the most aggressive of bitcoin investors might shoot to come closed to investing 100% of their disposable income into bitcoin, and surely there is value in being aggressive, yet at the same time, if they are investing close to 100% of their disposable income into bitcoin for long periods of time, they are likely going to be putting unnecessary and undue stress upon their finances and their psychology, especially since bitcoin is an asymmetric bet to the upside in which investors can lose up to 100% of what they put in, but there are also various great upside scenarios, so even relatively whimpy investors might well end up finding themselves to have had profited quite fantastically from their having had decided to p;ut some level of their disposable income into bitcoin (even if it was a relatively whimpy amount in the 1% to 5% territories.
None of us can decide the balance level for the investment levels of anyone else, so there can be ways to take a reasonably balanced or a somewhat aggressively leaning investment approach to bitcoin, and still maintaining a fair amount of balance and/or enjoyment in life because there is some value to spending some money while you are young rather than completely deferring gratification and neglecting your own psychological and/or social well-being that might sometimes be better off by spending some money while you live rather than completely deferring gratification based on choosing to invest on the high side of aggressiveness into bitcoin.
It is going to be risky for Bitcoin investors to invest 100% of their disposable income or accumulate aggressively, which may later negatively affect the investment for the duration of that emergency. I think I got the gist of what you said. If 10% or 20% of disposable income can be considered for investment, then the rest of the Floating Cash can be reserved for emergency needs and the amount of float should be such that the daily needs of the family can be met for 6 months or more. This arrangement is definitely going to be positive for long-term investment in the future as the amount of cash depends on increasing your Bitcoin stash and holding it for a long time.
