Dividing your investment into 3 and invest one part of it into Bitcoin is very wrong and it is not advisable to do that, what is advisable to use for our Bitcoin investment is 5-10 percent of our income depending because some persons have several source of income and so they can decide to use more than 10 percent from one of their source of income to invest. This 5-10 percent I'm talking about should be what one can be able to let go because Bitcoin investment is a long term investment that is if you actually want to get a good result or outcome from your investment because if you hold for long, your output will always be greater than your input.
If not for the fate that it is be better more to be a low coiner than to be a no coiner allocating only 5-10% of your income to invest in Bitcoin is too poor for me it is assume that you are scared to invest in bitcoin.
Bitcoin is not shitcoins if it's shitcoins you want to invest then i will advise to only use 5-10 % of your income since they are not to be trusted for there is possiblity that it can dump to nothing but i don't believe that Bitcoin can go to zero or even go below 60$.
It is not wrong if an investor decides to allocate 5-10 percent of his/her income for Bitcoin investment because you do not know how big the income of the investor is, or the 5-10 percent the investor decides to allocate for Bitcoin investment could be what the investor can possibly afford to invest in Bitcoin so that he/she will not go out of the game. Even if Bitcoin isn't a shitcoin, since Bitcoin is a long term investment, it is always advisable and important for investors to accumulate Bitcoin within their discretionary income even if the discretionary income is $10 so they can hold their Bitcoin investment for a long term.
It is quite understandable because investing 5-10% of our discretionary income into bitcoin won't really stress us that much compare to when we are investing an amount that will mount pressure on our finances. If there is slight changes or volatility in the market won't be exposing all our income to risk, and also investing in bitcoin for a longer term and holding until our portfolio is in profit
