You cannot invest or buy bitcoin daily. But weekly or monthly and a poor man cannot invest in bitcoin with one third of his discretionary income.
That's why its important before engaging on anything especially when dealing financial matters
people should try all they can to make their selves financially stable.
Surely You can say "
if they have a steady souce of income", instead of
"Being financially stable" because this statement has caused a lot of people not to start investing in bitcoin as they ought to have invested, simple because they misinterpreted the word Being financialy stable to mean rich. some may look like they need to be rich before investing while the actual sense is having a constant souce of income to front load your bitcoin and or your discretion fund to be able to invest comfortably and regular with what you can afford to lose either weekly or monthly.
Newbies don't even have to have a steady source of income to invest into bitcoin, yet they do need to have discretionary income, so if their income is less steady, then they likely need to keep more back up funds to cover periods in which their income might not be steady. The more unsteady their income, then the more back up funds that they likely need, especially if they want to invest in bitcoin, and if they think that they are not going to be able to get income in the future, they might have to stop investing in bitcoin until they are able to shore up their income situation.
