No body will invest all his salary in Bitcoin it is not done anywhere except the person is insane, the money will invest in Bitcoin is our Discretionary income and what is Discretionary income is the amount of money left for an individual to spend or use after sorting out his or her personal needs, so let's get this right and you can as well use your Discretionary income to build your backup funds along side your Bitcoin and if you are done building your backup funds you can focus on your Bitcoin accumulation and even become aggressive if you no it won't affect you.
One don't need to have enough money before he can go into Bitcoin investment, if you are receiving a little salary a full month and you wish to invest in Bitcoin you can, if after your monthly expenses you are lift with a Discretionary income.
Putting all your salary into bitcoin is insane and that should not be encouraged but discouraged by anyone that wants to do so. Your monthly income has to be flowing every month in order to enjoy your investment in bitcoin. If you’ve already used your monthly income for all the necessary things you need for the month and also save some for your emergency needs, you can now put some into your Bitcoin investment while making sure that the monthly flow of income is still intact and coming on a monthly basis.
Emergency cannot be foresee or curtailed when it has happened, so you need to have many options to rely on when you happen to find yourself in an emergency situation and not even think of using your bitcoin savings to solve the problem. Emergency funds saved after collecting your monthly salary can be of use in term of emergency and when your monthly income is still flowing, you can also take from their to solve the problem without even touching your investment. If for that month you can’t add more to your savings because of th emergency that arose, you can always continue the following month, the point is not to touch from the bitcoin investment already in the portfolio so that you’re not shortfall or drawback and be at loss again.
