There's no right time to invest in Bitcoin other than investing when your discretionary income is available, but if you see anyone that's waiting for the right time to buy Bitcoin, just know that the person isn't buying Bitcoin with a long term mindset, and the person will have to wait to buy Bitcoin when a dip occurs so that it will enable the person to sell his Bitcoin once the price of Bitcoin starts increasing.
Your comment is very vague.A person can start investing only if he has a source of discretionary income. Many people have their own income through which a person can invest but cannot continue to invest consistently or in the midst of a financial crisis, he sells his holdings. To maintain the continuity of investment and to keep the investment stress free, one should invest with discretionary income. Discretionary income is the amount of money that you have left after deducting all your expenses, that is discretionary income.
Your re right what's is needed to start an investment in Bitcoin is our discretional income and in most cases our source of income differs. There are some persons that doesn't have a regular income that's is ,there source of earnings comes once in a while. Persons like this has to do properly planning on their spendings that will cover all of their basics needs to sustain them for a certain periods of time knowing fully well that their next incomes will not be coming anytime soon. Investors like this cannot be consistent in their bitcoin accumulation but can only buy Bitcoin once their next income is secured.
However Emergencies situations is inevitable but future planning and preparation can help one to avert it when it struck. If one start building his emergency and reserve funds from his discretional income,then situations like this can be well managed until it is solved that one wouldn't be forced to sell his Bitcoin holdings.A successful bitcoin investment is all about planning, if one fails to plan it also means he is planning to fails.
