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 invest 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 invest either weekly or monthly.
