Of course, we look at bitcoin differently if we have already established some kind of an investment portfolio as compared if we are brand new to investing.

Prior to investing into bitcoin, I had mostly been investing into various kinds of index funds that would be a mixture of stocks and bonds, and then some property and business investments.  

When I first got into bitcoin, I created a 6 month budget for myself, so by the middle of 2014, my six months was over, so I largely extended my investing into bitcoin and my budget for another 6 months, so by the time that the end of 2014 came, I was attempting to reassess what I should do, and at that point, I had largely reached around 10% of my total investment portfolio to have been into bitcoin, so I thought that I had largely met my goal.. however, if you look at the charts, you will see that bitcoin prices continued to go down and to stay down through almost all of 2015, so my ongoing buying of BTC during 2015 had caused my BTC allocation to go higher than my 10% preference, and I had gotten up to around 13.5% allocated into BTC by the end of 2015.

I reassessed various times and tried to figure out what to do, an largely I decided not to reallocate my BTC.. but just let my BTC investment ride and to take various risk management (volatility) strategies within my BTC holdings by selling very small amounts (less than 1% of the holdings for every 10% the BTC price went up) on the way up and using that money to buy back.. so there can be some additional fees in that kind of a strategy, too.

Well maybe there were times in which I might have ONLY been making small amounts of money, so figuring out how to construct some kind of a savings plan, and so sometimes when my income went up at later points in my life, I did not feel that I needed to buy a bunch of stuff, so I could invest way more than 10%.. and maybe even getting up to periods in which I was investing 30% or more... but it was good to always have an ongoing practice of investing.. even though I believe that there were several times that I made mistakes in terms of taking some of the investment money and believe that I was investing into solid projects, when those investments were not very good... so for sure, over the years, mistakes can be made.. and even sometimes not very good management of where to put the money so that it could grow without too much risk.. .. but sometimes there would still be needs for some risk.

You can build up your investment portfolio and you can also live at the same time.. it is not an all or nothing proposition.  You can have some money in banks and some money that earns interest and some money in property or businesses, index funds and now days we have bitcoin... so then each of us have questions regarding how large our investment portfolio already is and how much of that we might want to put into bitcoin, how much cash do we want to have available or floating.  When I was younger, I did not need to have a very large float and I could project shorter periods of time forward, but it seems that as I grew older some of my finances and some of my financial instruments, business and family arrangements have caused me to have more complicated finances, so instead of projecting my cashflow out 6 months, I tend to project my cashflow out a couple of years, even though of course, the next 2-3 months are more urgent than later down the road, but if you do not project out ahead, you might not realize whether you might have a cashflow problem that might be coming up several months down the road...or even to figure out some of your potential cashflow issues a couple of years in advance can be helpful in determining how much of a cash cushion that you would like to keep on a regular basis and how much you want to keep in whatever emergency funds that you have so that you do not have to dip into your bitcoin investment at a time that is other than a time of your own complete choosing.
